Today we look at the accuracy of the Umarex Fusion 2 CO2 rifle.

The test

I shot the rifle from a rest at 10 meters. I wanted to give the rifle and scope an easy test, as I was actually looking for the most accurate pellets, in case I move back to shoot at 25 yards. I shot 9-shot groups with each pellet because the magazine holds 9 pellets.


The Fusion 2 doesn’t have open sights so I scoped it. I mounted a UTG 2-7X44 Scout SWAT scope. I mounted it quickly for today’s test with the intention of shimming it at the rear for a longer range test if the Fusion 2 was accurate.

JSB Exact RS

I sighted in with JSB Exact RS domes and then shot a 9-shot group. Nine pellets went into 0.637-inches at 10 meters. That would be okay for 25 yards but it’s big for 10 meters.

Fusion 2 RS group
Nine JSB Exact RS pellets went into 0.637-inches at 10 meters.

Air Arms Falcon

Next to be tried were Air Arms Falcon domes. They often surprise me with their accuracy. This time they turned in the smallest group of the test — 9 in 0.592-inches at 10 meters.

Fusion 2 Falcon group
Nine Air Arms Falcons went into 0.592-inches at 10 meters. It was the smallest group of the test.

Falcons also jammed the magazine three times. I spent as much time trying to fix the air rifle when shooting them as I did with all the other pellets tested.

Magazine problems

I had problems with the magazine in previous tests, but I thought they were all solved by holding the rifle level. Nope. Today the mag got jammed in the action three times, requiring me to tap it out with a punch. What happens is a pellet jumps out of the mag as it is loaded into the receiver. Once that happens the mag with neither go all the way into battery, nor can it be removed easily. Hence the drift. When it comes out the damaged pellet that was jamming it can be removed from the action, though I also had to pry pieces of one pellet out of the magazine with a small pen knife.

Fusion 2 magazine
I had to drive the magazine out of the receiver three times to clear jammed pellets!

The magazine also failed to advance several times, resulting in a blank shot. I resorted to watching it as I cocked the rifle to make certain it advanced.

RWS Meisterkugeln Rifle

I wanted to try a heavier pellet, so the RWS Meisterkugeln Rifle wadcutter was next. Nine of them went into a group that measures 0.549-inches between centers. It’s a very round group, but look at it. The pellets didn’t want to have anything to do with each other!

Fusion 2 Meister group
Yes, it looks like only 6 holes but 9 RWS Meisterkugeln Rifle pellets are in this 0.549-inch group.

H&N Baracuda Match 4.50mm heads

Now I wanted to try a really heavy pellet. Sometimes they can be very accurate in lower-powered airguns. Nine H&N Baracuda Match domes with 4.50mm heads made a 1.258-inch group at 10 meters.

Fusion 2 Baracuda Match group
Nine H&N Baracuda Match domes made a 1.258-inch group at 10 meters. It’s the largest group of the test.


Well — phooey! The rifle doesn’t get good gas mileage, it has a defective CO2 reservoir that needs a workaround, it won’t accept the 88-gram cylinders it’s supposed to, the magazines both jammed the gun and the thing isn’t accurate. At least that was my experience with it.


There are too many air rifles that have a lot going for them for me to recommend the Fusion 2. I had high hopes at the start of this report but the test gun derailed them.

  • A dime spacer
  • It worked!
  • Velocity
  • No feeding problems
  • Trigger pull

  • Where we stand
  • Summary

Today we look at velocity of the Umarex Fusion 2 repeating air rifle again. After Part 2 I considered all the remarks carefully. I wanted to test the rifle’s accuracy but not before knowing how many shots I could count on.

A dime spacer

Reader EricfromSC said he used a dime as a spacer between the two CO2 cartridges and it worked. He also mentioned that he had the same magazine feeding issues I encountered and that by holding the rifle level when working the bolt they were resolved. When I test velocity I often cock the rifle with the muzzle up, so this time I was careful to hold it level.

I first dropped about 10 drops of automatic transmission stop leak into the CO2 tube before dropping the first CO2 cartridge in. Then I dropped in a Crosman CO2 cartridge. Since they were the only brand that actually worked in Part 2 I felt I needed to stay with them.

The I dropped in the first cartridge, followed by a dime. I wondered whether the dime would tilt sideways in the tube and mess things up, but it fit like it was made for it.

Fusion 2 dime
You are looking halfway down into the Fusion’s CO2 tube. The dime is resting on the wide end of the first CO2 cartridge. The fit is perfect.

For those in other countries who don’t have American dime coins, I used a new coin. The diameter is 17.91mm and the thickness is 1.35mm. The dime fits loosely enough that sticking won’t be a problem.

It worked!

I’m pleased to say the dime trick worked and both CO2 cartridges were pierced quite well. Look at the holes.

Fusion 2 cartridges
This time both CO2 cartridges were pierced well. The bottom one that had all the trouble before is on the left.


I decided to only shoot the JSB Exact RS pellet, as it has no feeding issues last time. The first 9 shots gave an average 640 f.p.s. The low was 634 and the high was 652, so a spread of 18 f.p.s.

The second 9 shots averaged 642 f.p.s. The low was 633 and the high was 651, so  another spread of 18 f.p.s.

The third 9 shots averaged 623 f.p.s. The low was 605 and the high was 641 f.p.s. So the spread this time was 36 f.p.s.

The fourth 9 shots averaged 553 f.p.s. The low was 506 and the high was 590 f.p.s.

I will show you the fifth string.


I ended the test at this point to keep from sticking a pellet in the barrel. Without a doubt the Fusion 2 uses a LOT of CO2!

No feeding problems

Once I held the rifle level as EricfromSC suggested the feeding was perfect. But I will say that every time the bolt passes through the magazine you can see the mag move a little. So watch this!

Trigger pull

I didn’t give you the trigger pull in Part 2. The trigger is single-stage with a long smooth pull that maxed at between 3 lbs. 3 oz. and 3 lbs. 8 oz. The average was 3 lbs. 6 oz.

One final tip

It occurred to me that since I had removed the CO2 adaptor tube to try the 88-gram cartridge, it was now coming out of the rifle every time I installed new cartridges. Looking at the manual I see that it’s not supposed to do that. So here is my tip. First, screw the adaptor into the rifle as far as you can, then load the two cartridges with the dime between. When you screw the knurled end cap down, leave the relief valve open so you can hear when the lower cartridge is pierced. The knurled end cap will allow you to screw the adaptor down as far into the rifle as it will go. When the hissing starts, screw the relief valve down as far as it will go. The hissing stops right away but keep turning the valve until it stops to pierce the top cartridge fully. I conducted several experiments to determine this was the most reliable way to pierce both cartridges! I do not care for this design! 

Where we stand

Now that the rifle is working and I know its quirks I’m ready to move on to accuracy testing. I hasve read so many good things about the accuracy that I’m looking forward to it.

I would like to thank EricfromSC for his comments to Part 2. Without them I don’t think I could do an accuracy test on this rifle.


I have this to say about the Fusion 2. It has some shortcomings that I was able to overcome with help. I wish the magazine was more positive and why can’t I still get the 88-gram CO2 cartridge to pierce. Those things need to be addressed. But if you own one, I hope today’s report helps you.

Umarex Fusion 2 CO2 rifle: Part 2

Part 1

This report covers:

  • A 2-cartridge CO2 reservoir
  • The test
  • RWS Hobby
  • JSB Exact RS
  • Didn’t work
  • The Umarex 12-gram adaptor?
  • Back to the original 12-gram cartridge adaptor
  • RWS Hobbys a second time
  • JSB Exact RS a second time
  • H&N Baracuda Match
  • Magazine troubles
  • Summary

Today we look at the velocity of the Umarex Fusion 2 CO2 rifle. I read the customer reviews before testing the rifle, which I usually don’t do. I did it to see if there was anything I should watch for. Well they were all over the place, with the most common complaints being about the 12-gram CO2 adaptor and a loose magazine that flops around. I will disregard the comments about CO2 costing too much. Guys — this rifle runs on CO2! What are you thinking?

But two comments mentioned the CO2 cartridges were hard to pierce, or they leaked down too fast. That I will watch for.

A 2-cartridge CO2 reservoir

What I’m about to say applies to all airguns that use two 12-gram CO2 cartridges. Most of them work the way they do in this Fusion 2. They go in nose-to-nose and the last cartridge you put in presses the first one down on a piercing pin. In the Fusion 2 manual the CO2 cartridge piercing assembly is called the “relief valve assembly” which is a confusing term to me, since piercing the cartridges is its primary function.

The test

I’m going to test the Fusion 2 with several pellets and there are already 9 shots on the two 12-gram cartridges that I installed 9 days ago. We will see how well the rifle holds CO2!

Since the magazine holds 9 pellets my strings will be 9 shots, rather than 10. Let’s get started.

RWS Hobby

The first pellet tested was the RWS Hobby. The average for 9 shots was 651 f.p.s. but I will show every shot.

9………….Nothing came out

As you can see, this isn’t a standard shot string. These are shots 10 through 18 on two fresh 12-gram cartridges installed the previous week. But the velocity should be stable — not falling constantly.

What about shot number 9? Well, On the first shot the pellet did not want to enter the breech. I later found that pellet had been deformed by the bolt probe and was drawn back into the bolt pathway, where it lodged for awhile. I will have more to say about this in a bit.

JSB Exact RS

Next up was the JSB Exact RS dome. I won’t give you an average but I will show the entire shot string.


Obviously the gun is running out of gas. I removed the CO2 cartridges and found that the last (top) one in had been pierced but the first (bottom) one had not been pierced. This is one of the complaints customers reported. These are both Umarex CO2 cartridges, as recommended.

Fusion 2 cartridges
Both Umarex cartridges were in the Fusion but the one on the right wasn’t pierced.

I know how to pierce 2-cartridges in a CO2 gun! I did everything right and it still didn’t work! Okay, the 2-cartridge adaptor doesn’t work very well — I’ll put in an 88-gram cartridge! I didn’t have Umarex cartridges but thankfully I did have a couple from Sig.  

Didn’t work

This big cartridge just screws in until it is pierced, but it also failed to pierce when screwed down tight. I even used ChannellLock pliers to tighten it down as far as it would go, but no luck.

Fusion big cartridge
The 88-gram CO2 cartridge was not pierced. That round divot is where it was in contact with the piercing pin.

The Umarex 12-gram adaptor?

Umarex sent me a 2-cartridge adaptor for testing the Air Javelin. I gave that a try as well . Both cartridges pierced but the piercing pin inside the rifle did not open the valve in the adaptor.

Back to the original 12-gram cartridge adaptor

I was getting frustrated by this point, so I went back to the 12-gram adaptor that came with the Fusion 2. Umarex says not to use Crosman 12-gram cartridges because their necks are too small, but since Umarex cartridges didn’t work I tried them anyway. This time I had success piercing both cartridges. I’ll show that in a moment but first let’s look at velocities again, now that the rifle is charged.

RWS Hobbys a second time

This time Hobbys gave an average of 658 f.p.s. with a spread of 25 f.p.s. It’s large but acceptable. The low was 649 and the high was 674 f.p.s.

JSB Exact RS a second time

The second time with JSB RS pellets gave an average 665 f.p.s. The low was 662 the high was 672 f.p.s. I’ll take a 10 f.p.s. spread!

H&N Baracuda Match

Now for Baracuda Match pellets. Instead of an average I’ll show the string.

5………….did not register

It seemed like the rifle was doing okay during this string, even though I missed the velocities of three of the nine shots. So I shot another 9-shot string of Hobbys, now that we have good data.


I think you can see that the rifle is running out of gas again — after just 36 shots! This rifle must be leaking pretty fast to run out of two 12-gram cartridges in only 36 shots at such low velocities. Let me show you the ends of the two Crosman cartridges.

Fusion Crosman carrtidges
The Fusion was able to pierce both Crosman 12-gram cartridges. The one on the right is difficult to see but I examined it with a magnifying glass and it does have a large hole.

Magazine troubles

What I haven’t mentioned yet is that while all this was happening I was also having problems with the rotary magazine. It doesn’t like to be inserted into the receiver and even when it is, it moves around as the bolt pushes pellets out of it. Remember that first string of only 8 shots? Here is what happened. As I tried to seat the mag the first pellet popped up and got mangled. Look here.

Fusion Mag jam
While inserting the magazine the first pellet popped up like this.

Clearing that jam tore the partition between two of the pellet chambers — ruining the magazine. I had to do this three times during today’s testing.

Fusion ruined mag
Clearing the jammed pellet(s) and magazine from the Fusion tore the partition between chambers 1 and 2.


This test disappoints me — not because there were problems with the test rifle, but because they are the same problems already reported by several owners. That tells me there is an entire shipment of Fusion 2 rifles that potentially have the same problems.

I will have to consider what to do next. I doubt I will ask for another rifle to test, because the possibility of the same things happening seems high. I could possibly test the accuracy of this rifle, which customers all agree is quite good. But I have to think about it.

One possibility, and this is a note to myself , is to try lubing the cartridges with ATF stop leak in hopes of repairing the seals inside the gun.

The TAC-4.5 from ASG is a 21-shot BB repeater.

Accuracy day

Today we learn whether the TAC-4.5 BB gun from ASG can shoot. We already know it is quiet, has a nice trigger and is very conservative with gas. Accuracy is the cherry on the sundae. The distance was 5 meters.

Air Venturi zinc BBs

The first BB tested was an Air Venturi silver (zinc-plated) BB. Seven of them went into an incredible 0.727 inches at 5 meters. The other 3 BBs opened the group to 1.877 inches. I think those 3 shots were caused by aiming errors, because the front sight has an red fiberoptic bead that is larger than the entire bull on a 10-meter rifle target.

TAC 4.5 BB gun Air Venturi BBs
Ten Air Venturi silver BBs went into 1.877 inches at 5 meters, but 7 of them went into just 0.727 inches.

I shot the gun off an MTM shooting bench, using the bipod that came with the gun. If that hadn’t been as stable as I liked I would also have shot it off a UTG Monopod. But the bipod that’s packed with the gun is very stable.

Daisy BBs

Daisy Premium Grade BBs were loaded next. Ten went into 1.486 inches. These BBs were the most variable in size in Part 2 when I measured them, but they did okay on paper.

Ten Daisy BBs went into 1.486 inches at 5 meters.

ASG Blaster BBs

Next in line were ASG’s own Blaster steel BBs. Ten of them went into 1.716 inches, but one of them was a flier. Nine are in a tight 1.025 inches. As I said before, that front bead is so large that I’m sure there was a large error from aiming.

Ten ASG Blaster BBs went into 1.716 inches inches at 5 meters, but 9 of them are 1.025 inches.

Air Venturi copper BBs

The last BB I tried was the copper-plated Air Venturi BB. Ten of these went into 1.582 inches at 5 meters. I though they would be the best, when in fact they were in the middle of the accuracy scale.

Ten Air Venturi copper-plated BBs went into 1.582 inches inches at 5 meters.

Overall evaluation

I think the ASG TAC-4.5 is a fine BB gun. It’s quiet, gets great gas mileage and has a good trigger. Accuracy isn’t stellar, but I think that’s more on the front sight than on the overall gun. If you like quiet BB guns, this one is for you.

The 2015 Texas Airgun Show

Just a reminder that the Texas Airgun show is coming up fast. Edith asked me to go through with the show regardless of what happened, so of course I will do it for her.

Door prize

This year’s door prize will be a Condor SS, generously donated by AirForce Airguns. Everyone who pays admission to the show will have an equal chance to win this fine sporting PCP that AirForce will accessorize with a scope, rings and perhaps a bipod. That’s a lot to win for the price of admission! And, if our estimates are correct, there should only be 500-600 people attending the show (about 400 came last year), so your chances of winning are very good. The competitors in the big bore airgun match (LASSO) will get admission to the show and a chance at the door prize included included in their $20 match entry fee.

Big bore match

Speaking of the LASSO big bore match, it’s back, after 3 years hiatus. There are 2 classes — varmint (under .40 caliber)  and big game (.40 caliber and larger) and they will compete on a course that extends out to 250 yards. The targets are challenging and realistic for hunters.

For the grand prize Crosman Corporation has generously donated the very .357 Bulldog rifle that I tested for this blog and also wrote up in the color issue of Shotgun News that’s currently on the newsstands. Not only will the scoped rifle be awarded, it will come with a certificate of authenticity signed by me that proves it was used for the feature magazine article. The winner will also get a copy of the color issue of Shotgun News that contains that article. And Crosman has included two boxes of their Benjamin Nosler Ballistic Tip bullets. This is a very important grand prize!

Raffle prizes

In addition to the door prize there will also be several raffle prizes — drawn throughout the show. Among them are a .357 Carnivore QE big bore rifle from Hatsan USA, a Diana RWS model 34 from RWS USA, a Legends P.08 Blowback pistol from Umarex USA, an Airburst MegaBOOM Supersonic Target System with pump from MegaBOOM and several smaller prizes from Umarex USA. Pyramyd Air has not yet announced the airgun they will donate (my fault, not theirs), but I expect it to be another very desirable airgun. And there are other dealers attending who may still donate to the raffle drawings.

Action pistol competition

MegaBOOM and Umarex USA are also hosting an action pistol match that’s open to the general public. Just pay the nominal entry fee and the guns and ammo will be supplied. The targets are all MegaBOOM action targets and the MegaBOOM company has said there will be a nice cash prize for the winner. All proceeds for the match will be donated to the Parker County Sportsman Club that hosts the airgun show.

A firearm show — too

One special thing about this show is that firearms are permitted as well as airguns. You have to be a Texas resident to buy and sell firearms, and all federal and state regulations apply. I also know that a famous maker of automatic knives will have a table and will be selling some fantastic creations. Automatic knives are now legal in the state of Texas.

Last year we had several tables with firearms and people who just attended also brought them to the show. This year I expect a lot more firearms because the members of the Parker County Sportsman Club that is hosting the show saw the huge turnout we had at last year’s show. And the crowd came to stay all day and had lots of money in their pockets. So if you are a Texas resident, don’t miss this chance to attend a dynamic gun show!


The evening before the show we will host a reception at the Texas Star Ranch and Retreat. It’s located along the road that runs from the hotel to the gun club, so show-goers will be able to find it quite easily. The reception starts at 6 p.m. and run to 8 p.m., during which we will film a special segment of the Round Table for the American Airgunner show. We are going to try to get some audience participation into this one. Light refreshments will be available, but have your dinner either before you come or after.

TAC-4.5 BB gun: Part 2

by Tom Gaylord
Writing as B.B. Pelletier

Part 1

TAC 4.5 BB gun
The TAC-4.5 from ASG is a 21-shot BB repeater.

This report covers:

  • ASG Blaster BBs
  • Daisy BBs
  • Air Venturi BBs — silver
  • Air Venturi BB container is the best!
  • Air Venturi BBs — copper
  • ASG velocity for the TAC-4.5
  • This BB gun is quiet!
  • Shot count
  • Trigger pull
  • Overall evaluation

Today is the velocity test of the TAC 4.5 BB gun. This airgun operates on a single 12-gram CO2 cartridge that is housed in the grip. In Part one I showed you how the spring-loaded backstrap flips back to reveal where the cartridge goes.

I noted there was very little gas escape when I pierced the cartridge, and the gun seems very quiet. But a hole in the backer cardboard told me the gun definitely shot.

ASG Blaster BBs

I’m going to get right to it today. The first BB I’ll test is ASG’s Blaster steel BB. I measured 5 of them, and the diameter ranged from 0.171 inches to 0.173 inches. One of the five was out of round by a thousandth of an inch. The other four were regular. This BB is on the smaller side of what is normal for BBs today (0.171 to 0.173 inches), and the variation in size is greater than I have seen. We will see what that means, as far as accuracy is concerned.

These BBs averaged 364 f.p.s. The high was 407 and the low was 344 f.p.s. That’s a 63 f.p.s. spread. The decline in velocity was very linear, despite my waiting a minimum if 10 seconds between shots.

Daisy BBs

Next to be tested were Daisy Premium Grade BBs. They are the standard BB I use in many of my tests, because they are so uniform and accurate — I thought. I measured 5 of them and got a range of 0.1695 inches to 0.172 inches, which is both smaller and a lot greater spread than I was expecting. They averaged 355 f.p.s., with a high of 370 and a low of 350 f.p.s. The velocity drop was steady until they hit 350 f.p.s., then they stayed there. The spread with this BB was only 20 f.p.s, so they are much more consistent, if not quite as fast.

Air Venturi BBs — silver

I noticed that Air Venturi has brought out a line of BBs, so I ordered some and decided to start testing them with the TAC-4.5. The silver (zinc-plated) BBs measure 0.1715 to 0.172 inches, which is more uniform than the first 2 BBs tested. They also measure as perfect spheres. In the TAC 4.5 they averaged 375 f.p.s. with a high of 405 f.p.s. and a low of 363 f.p.s. The high was in the middle of the string — the first shot after I had to take an unscheduled break from testing, and more than 5 minutes had elapsed, so the 62 f.p.s. spread was artificially high. The velocity dropped on each shot as it had with the first 2 BBs, but it seemed to bottom out in the mid 360s. I will also include this new BB in the accuracy testing.

Air Venturi BB container is the best!

Before I move on, I want to say a word about the plastic bottle the Air Venturi BBs come in. It is the best BB container I have ever seen! It has a pour spout that comes to you already open, so there is no need to cut stiff plastic and risk cutting yourself. And the pour spout is just the right size to allow BBs to pour out. Some spouts are the right size for the BBs to jet jammed in the opening and release one at a time, causing no end of frustration. Also, the cap screws on the bottle instead of just popping on with pressure. That gives you positive control over opening and closing the bottle and it will never pop open on its own if it falls off a table. I have has each of these problems with other BB containers. Well done, Air Venturi!

Air Venturi BBs — copper

I also tried the copper-plated Air Venturi BBs. They measured 0.1715 to 0.172 inches — the same as the zinc-plated BBs. Air Venturi has brought out two superior BBs that you really should try. These BBs averaged 370 f.p.s. with a high of 385 and a low of 356 f.p.s. That’s a spread of 29 f.p.s. The decline in velocity was very similar to the Air Venturi zinc-plated BBs, but I didn’t have to stop in the middle of the test this time.

ASG velocity for the TAC-4.5

ASG says the velocity of the TAC-4.5 is 417 f.p.s. The highest seen in today’s test was 407 f.p.s., which is close enough. But some of you may be confused by the velocity report. Why is this gun rated at 417 f.p.s. when it only averaged 350-360 f.p.s. for several strings of 10 shots? The answer is liability. Manufacturers state the highest possible velocity for their airguns, so the buyer knows what he is getting. An easy way to think of this is to ask yourself the question, “What is the worst it can do” or how dangerous is it? The rated velocity tells the buyer how powerful the gun can be at its maximum.

Many people think manufacturers purposely over-state the velocities of their airguns to get more sales, and in some cases that is true. The spring gun makers who rate their guns at 1600 f.p.s., when that speed is impossible to achieve without a detonation of some kind, are doing that. With the TAC 4.5, though, the stated maximum is both real and correct.

This BB gun is quiet!

I see where the sound level of the Pyramyd Air website is set at a 4 out of 5, which is pretty loud. In truth, the gun I am testing is on the low end of a 2. But let’s not go on the warpath about that, because Edith is the one who makes those changes. It may be a while before she can fix that. That is one of the benefits of my testing airguns, because any time I encounter something that doesn’t line up with the description, I just tell Edith and she fixes it in minutes.

This gun is so quiet that it is perfect for apartment dwellers and those wishing to shoot in small suburban yards. I just want you to know that, because for some buyers it makes a very big difference.

Shot count

Another place I was surprised in this test was by how many shots I got on a single CO2 cartridge. Given the average velocity and the fact the gun does not have blowback, I guessed it might get something around 100 shots. In fact, the gun was still shooting Air Venturi copper-plated BBs at 356 f.p.s. on shot number 116. Shot 178 went out at 314 f.p.s. and I stopped shooting at 201 shots, when the velocity had dropped back to 272 f.p.s. That makes the TAC-4.5 the second most gas-conservative CO2 BB gun I have tested since I started testing airguns in 1994! Only the Czech APP 661 pistol got more shots (from an 8-gram cartridge, no less!), but it only shot BBs at 250 f.p.s.

Trigger pull

The trigger pull is double action only, since the trigger is pulling the striker back against a spring. It does not have to advance a cylinder, which decreases the effort a lot, but its still a double action pull. The effort required is a pretty consistent 5 lbs. 6 oz. I found it pleasant and very light for double action.

Overall evaluation

So far I think this BB gun is a winner. I think it’s what a lot of you BB gunners have been looking for. Accuracy testing comes next, but like I told you un Part 1, I’m not looking for a target gun

• RWS Superdome pellets
• Final evaluation

Today, I’ll back up to 25 yards and see what the Crosman 1077 CO2 rifle can do at that distance. I used a vintage Tasco Pro Point dot sight because, when I mounted the Tech Force 90 dot sight, it was angled too far to the right. So, the shots landed too far left. The Tasco was similarly skewed, but it wasn’t as pronounced, and I was able to adjust the impact point back to where I wanted it.

Crosman Premier Lite pellets
The first pellet up was the Crosman Premier lite domed pellet. Even after sight adjustments, it was still shooting too far to the left and was off the target paper. Ten shots made a group about 2 inches between centers, but I didn’t measure it. That’s just a guess. Premier lites are out for the 1077 at 25 yards.

Air Arms Falcon pellets
The next pellet I tried was the Air Arms Falcon that did so well at 10 meters. They landed in the bull a little below center, but I noticed they seemed to be going slower on every shot. The group was visibly strung out vertically.

Ran out of gas
I have had the 88-gram CO2 cartridge in the rifle for several years and shot it hundred times, so it was running out of gas. When I removed it, it didn’t have much gas remaining. A new cartridge was installed and the gun was back up to snuff.

I shot another 10 Falcon pellets. This time, the impact point was 3 inches above where it had been before the gas cartridge was changed and 1 inch to the left. But this group was very telling. Ten went into 1.391 inches, but 9 of those are in 0.803 inches — and there’s a cluster of 7 that are in 0.384 inches. This is phenomenal 25-yard accuracy for a rifle in this price range!

Pretty good shooting for 25 yards. Ten Falcons are in 1.391 inches, but 7 are in just 0.384 inches.

This should answer the question of whether or not you can shoot well with a dot sight. Remember that this is a repeating air rifle, and I’m shooting out of a 12-shot clip. These pellets are being blown into the breech and are still capable of fine accuracy.

JSB Exact RS pellets
I didn’t want to shoot wadcutters because 25 yards is about where their accuracy fails, so I called up a couple pellets not yet tried. The first was the light JSB Exact RS. I adjusted the sight to strike the target lower, and these pellets hit about 2 inches below the center of the bull. They were also over to the right, but I did not adjust for that.

Ten RS pellets went into 1.585 inches, and 9 of them are in 1.071 inches. This time, there’s no smaller group within the large group, so I think the RS pellets aren’t as accurate as Falcons in my 1077.

Ten JSB Exact RS pellets in 1.585 inches at 25 yards, with 9 in 1.071 inches. Not quite as good as the Falcons.

RWS Superdome pellets
For the final pellet, I selected the RWS Superdome that often turns in remarkable results. I adjusted the dot sight up and to the right, and these pellets landed in the bullseye. Ten Superdomes went into 1.684 inches. As you can see, the group is fairly open. Nothing to make me think Superdomes might do better than this.

Of course, I haven’t tested the 1077 with a lot of pellets that usually do well. There might be something even better than Falcons. But I think I’ve shown how well the rifle can shoot when fed pellets it likes.

Final evaluation
The Crosman 1077 is a tremendous value in a repeating air rifle. It’s rugged, accurate and needs nothing more than pellets and CO2 to get the job done. If you’ve been wondering whether or not this is a good buy, read this test to decide. I’ll never get rid of mine!

1077 rifle
Crosman’s 1077 RepeatAir is a classic.

This report covers:

• Some old business — trigger-pull
• Today’s test
• First up — Crosman Premier lite pellets
• Air Arms Falcon pellets
• H&N Finale Match Pistol pellets
• Evaluation so far

Today we’ll look at the accuracy of Crosman’s 1077 CO2 rifle. Just as I said, it’s pretty impressive for an air rifle in this price range.

Some old business — trigger-pull
One of our readers asked me if the 1077 trigger-pull would be too heavy for a 9-year-old girl. I said it would on a new gun; but that I have an older gun whose magazine mechanism is broken-in, and I thought it would be okay.

I told you last time that the rifle I’m testing has a trigger-pull of 8 lbs. I guesstimated that the old rifle’s pull was about one pound lighter; but I wasn’t positive, so today I pulled out my old 1077 and measured the trigger-pull for you. Surprise, surprise! The old rifle’s pull measures 8.3 lbs.! Why did I believe it was so much lighter? I think it has to do with how smooth the worn-in mechanism has become. There’s no pause or hesitation when you pull this trigger like there is on the newer gun.

I also told you that the pull was mostly governed by the magazine mechanism that advances the pellet clip. Therefore, I installed the old magazine in the test rifle and tried the trigger. The pull did not change. So, shut my mouth — I was wrong! I’ve been telling people this for years, and perhaps there’s some truth to it if you compare a broken-in magazine to a brand-new one; but the gun also has to wear in for the trigger-pull to smooth out.

Oh, and for that reader who asked about the 9-year-old — yes, I think she could handle the broken-in trigger. It would seem heavy to her, but I think she could manage it.

Today’s test
I am shooting from 10 meters rested. Each target will get 10 shots with open sights. Since this is a gas gun and has virtually no recoil, there’s no special hold required, so I’m resting the rifle directly on the sandbag.

First up — Crosman Premier lite pellets
The first pellets I tried were the Crosman Premier lite domed pellets that weigh 7.9 grains. They put 10 into 0.761 inches at 10 meters. I think it looks more impressive than it sounds.

When I saw this first 0.761-inch group of Crosman premier lites, I knew my 1077 was going to shoot just as I told you!

RWS Hobby pellets
Before I get to what the RWS Hobby pellets did, I want to tell you how I controlled the group to get only 10 shots. As you know, the 1077 has a 12-shot circular pellet clip. What I did was load all 12 chambers and then shot just 10 shots. After that, I removed the magazine, popped out the clip and removed the last 2 pellets with a ballpoint pen. I think that’s easier than trying to orient 2 empty chambers in the clip when you insert the magazine.

I’m telling you this because I forgot to stop shooting with Hobbys. It’s a 12-shot group instead of 10 shots. The 1077 is so easy to shoot that it reminds me of its firearm namesake — the Ruger 10/22.

Twelve Hobbys went into a 0.63-inch group at 10 meters. How about that? More shots, yet a smaller group!

Air Arms Falcon pellets
Because I read the things I write and also believe them, I next tried Air Arms Falcon pellets. I’ve told you that Falcons are often accurate in lower-powered .177 airguns, and I couldn’t resist seeing if that was true for the 1077. Glory be — this time it was! Ten (I remembered to stop shooting at 10 this time) Falcons went into a 0.596 inch group that turned out to be the smallest one of this test.

H&N Finale Match Pistol pellets
The last pellet I tried was the H&N Finale Match Pistol pellet that sometimes surprises me with its accuracy. This time, they matched the RWS Hobbys with a 0.63-inch group. Of course, there must be small errors in measuring and one pellet might be fractionally better than the other.

The Finale Match group is vertical, which leads me to wonder if the gas is running out in the 88-gram CO2 cartridge that’s on the rifle. It’s been there for several years and for an undetermined number of shots.

Evaluation so far
The 1077 is turning out exactly as I remembered, except for the trigger-pull issue mentioned above. It’s a very accurate rifle that deserves a longer accuracy test. So, I’ll mount the Tech Force 90 dot sight and back up to 25 yards next time.
