Today, we’ll look at the velocity of the Daisy 880 multi-pump pneumatic. The test didn’t go as I expected it to, so stick around and learn something new with me.
Oil the pump head
Before I started the test, I oiled the 880′s pump head with several drops of Crosman Pellgunoil. I do that whenever I want to get the maximum performance from a multi-pump pneumatic, because the oil seals the pump head, allowing it to build more pressure.
First test — velocity per pump stroke
This is a test I recommend to all multi-pump owners. You test the velocity of your gun with differing pump strokes — from the lowest number recommended in the manual, which is 2 in this case, to the highest number, which is 10. [Note: In part 1, I stated that the minimum number of pumps was 3. It's actually 2, and the Pyramyd Air website has been corrected to reflect that.] For this test, I also did 11 and 12 pump strokes to see if the gun had even more velocity. The results were revealing. I’ll discuss them in a moment.
The pellet I used was the 7.9-grain Crosman Premier dome. Any pellet will do, but it helps if you always pick the same one in case you ever want to compare one gun to another.
* No air remaining in the gun after this shot.
For those who may be new to multi-pumps, notice that as the number of pump strokes increases, the amount of the velocity increase grows smaller. If you were pumping the gun, you would have noticed that after the fourth pump stroke (from 5 strokes on) the pump handle jumped out when I pulled it for the next stroke. Compressed air is remains in front of the pump head and does not enter the gun’s reservoir. As the pressure inside the reservoir builds, it holds the inlet valve closed a little harder each time; so, more compressed air fails to enter the reservoir. This phenomenon is common to all multi-pumps, and many of the more expensive ones have (or used to have) adjustable pump heads that minimize this; but the 880 doesn’t have any adjustment.
Note that there’s no air remaining in the gun after a shot was fired on 10 pumps. That means the gun is able to exhaust all the compressed air. From the velocity chart, we learn there’s no value in pumping the gun more than 10 times.
This is where I learned a couple big lessons about the 880 — or at least about my 880. Normally, a multi-pump is very consistent. The same number of pump strokes will give nearly the same velocity every time, as long as the same pellets are used. I’m used to seeing a velocity variation of about 5-8 f.p.s. over a 10-shot string. But not this time!
The 880 gave an average of 469 f.p.s. for 10 shots with 5 pump strokes. If you look at the string before, however, you’ll see that this velocity is well below what I got with 5 pump strokes (530 f.p.s.) and the very same pellet. Even stranger is the fact that, on this test, the velocity spread went from a low of 441 f.p.s. to a high of 502 f.p.s. That’s a variation of 61 f.p.s. over 10 shots. And not one of those 10 shots went as fast as the same pellet did on 5 pump strokes in the previous test!
The Daisy 880 varies greatly in velocity from test to test. You may think this is because my 880 is an older one. I can’t argue that. If you want to run the same test with a more modern 880 and submit your results, I’d be glad to see them, but please back up any claims you make with chronograph results.
RWS Hobby pellets
Next, I tested the rifle with RWS Hobby pellets fired on 10 pumps. These pellets averaged 600 f.p.s.; but, once again, the spread was very large. The low was 559 f.p.s. while the high was 643 f.p.s. That’s a variation of 86 f.p.s.
How fast will it shoot?
I tried a string of Crosman Super Sonic pellets on 10 pumps. They averaged 690 f.p.s. Again, the spread was very large — from 648 to 722 f.p.s. That’s 74 f.p.s. I only did this to see how fast the gun could shoot. The owner’s manual online says the maximum is 715 f.p.s with pellets, and we saw just a little more. So, that claim is right on.
Finally, I tried the rifle with Daisy Premium Grade BBs. On 5 pumps, they averaged 578 f.p.s. with a low of 565 and a high of 586 f.p.s. On 10 pumps, they averaged 644 f.p.s., with a low of 632 and a high of 657 f.p.s. So the gun is much slower than advertised (750 f.p.s.) with BBs, but the velocity spread is a lot less than it is with pellets.
I was surprised by the large velocity variation I saw with the 880. This is not just the largest variation I’ve ever seen with a multi-pump, it’s many times larger than the next largest variation. Multi-pumps are very consistent, in my experience.
Will this large variation have any affect on accuracy? Probably not at 10 meters, but it almost certainly will at 25 yards. I plan to shoot the rifle at both distances, so we shall see.

The $100 PCP is built on a Crosman 2100B chassis.
This test was very interesting! It began last week at my outdoor rifle range. Blog reader GunFun1 asked me to try shooting steel BBs in this gun because it was originally built to handle them (when it was in its Crosman 2100B form). I didn’t want to do it because this rifle launches the first couple shots at over 900 f.p.s., and steel BBs rebound like crazy (You’ll shoot your eye out), but I did relent. Last week, I took this rifle to my outdoor range and stuck a 12-inch Shoot-N-C target on the plywood target backer. I then paced off 10 meters and fired 10 BBs at this target.
I thought the BBs would probably miss the target altogether. I said as much to GunFun1 in my comments a few weeks ago. But they didn’t!
I was wrong about this. Shooting offhand with open sights, I put 10 Daisy Premium Grade steel BBs into 1.56 inches. It was actually 11 BBs. I must have miscounted during shooting. I was astounded! This isn’t just good — it’s great! You don’t shoot BB guns at 10 meters when you’re shooting groups!
Incidentally, all 10 BBs apparently went through the plywood target backer. Of course, there are other bullet holes there, so the wood isn’t always present or at its thickest; still, it shows those BBs are moving!
That got me wondering just how accurate this rifle could be. I decided to shoot from 25 yards with open sights, only. I’ll come back and shoot with an optical sight of some kind, but this test is just open sights.
I filled the gun to 2,000 psi for every 10 shots, including for the BBs shown above. After 10 shots, the gun’s pressure has dropped to 1,000 psi.
Crosman Premier lite
The first group of 10 shots was shot with Crosman Premier lites. Based on the 10-meter results for the last test, and also from where the BBs went, I adjusted the rear sight to the right just a little. After the first shot, I looked through the spotting scope to affirm it hit the target. It did, was high above the bullseye and fairly well-centered left and right. So, I left the sights where they were and fired a second shot. When I looked through the spotting scope, I saw it had gone through the same hole as the first! Wow! That was starting out well!
The first 4 shots all went into the same hole. Then shot 5 went higher for some reason.
After taking the picture of the first 5 shots, I shot the remaining 5 shots. That was informative because all the shots spread out to the left. Having the first 5 shots on record allowed me to see that the second 5 were the ones that actually spread out. The 10-shot group measures 1.358 inches between centers.
Next up were RWS Hobby pellets. They did quite well at 10 meters, but 25 yards is about the maximum distance at which wadcutter pellets hold their accuracy.
I adjusted the rear sight down one notch before shooting this group. Once more, I photographed the target after 5 shots.
Air Arms Falcons
The last pellet I tested was the Air Arms Falcon pellet. This time, the first 5 pellets didn’t seem to do that well. And when we see the final 10-shot group, it isn’t that much larger.
Conclusions so far
This experiment is turning out much better than I had hoped. Not only have we demonstrated that it’s possible to make a precharged pneumatic rifle that can retail for under $100, we’re now showing that it can really perform! Of course, the production gun will get many more shots on a fill than the 10 I’m getting, but I do think the maximum fill pressure should be held to 2,000 psi. That will make it easier to build an affordable hand pump, which Dennis Quackenbush is thinking about right now.
The discharge noise of this rifle is quite loud. I was going to recommend not putting a shroud on the gun, but I’m going to change my mind on that point. The customers for this gun will be suburban shooters who need a quieter air rifle, so some sound dampening is necessary.
The trigger on the rifle is heavy, and I would leave it the way it is. I would also leave the bolt-action exactly the way it is on the 2100B. The same goes for the sights. These are refinements people can pay for on higher-priced PCPs. We want to hold the cost of this gun to less than $100 retail.
I do plan on returning to test this rifle at least one more time with an optical sight. That will show the maximum accuracy potential, although I believe we’ve already seen a good indication of it in this test.
The $100 PCP will never replace the higher-priced PCPs that are already selling. It isn’t supposed to. It’s supposed to provide that entry-level step for those who are curious about precharged airguns and don’t want to spend a fortune to find out. I think it’s a very feasible goal and, quite possibly, a profitable one, as well.

Today is a special test of the C96, requested by blog reader RidgeRunner and seconded by several others. You want to see if the pistol will be more accurate with Daisy’s Avanti Precision Ground Shot, which is made expressly for the Avanti Champion 499 BB gun. More accurate than what? More accurate than the best BB tested in Part 3, which turned out to be the Daisy Premium Grade zinc-plated BBs that shot the tightest groups with this pistol?
We know that the Daisy Premium Grade BB averaged 395 f.p.s. with a total velocity spread of 18 f.p.s. (from 386 f.p.s. to 404 f.p.s.). RidgeRunner suspected the Precision Ground Shot would be faster in this pistol because it’s usually slightly larger and also more uniform. So, I first shot it over the chronograph.
Avanti Precision Ground Shot averaged 381 f.p.s. on a fresh CO2 cartridge. The velocity spread was 19 f.p.s., with a low of 371 f.p.s and a high of 390 f.p.s. The spread was 1 f.p.s. larger with this shot than with the Daisy Premium Grade BBs, and the average velocity was 14 f.p.s. slower. So, that part of the theory didn’t test out.
On to the accuracy test
I offered to do a blind test, but RidgeRunner trusted me to try my hardest with each BB: and that’s good because there’s a definite difference in appearance between the Premium Grade BBs and the Precision Ground Shot. The latter are not as shiny and appear more silver than steel in color than the Premium Grade BBs. I would have known which BB I was shooting.
The distance was the same 5 meters that was used for the first test, and I used the back of a chair to steady my hands as I held the pistol, just like I did before. This resulted in a very stable hold for every shot.
Daisy Premium Grade BBs
I shot 2 groups of 10 with each BB. The first group of Daisy Premium Grade BBs measured 1.115 inches between centers. Two BBs landed outside the black bull. The second group measured 0.644 inches between centers. That’s almost half the size of the first group, so you can see how much latittude there is with BBs — even at 5 meters.
Avanti Precision Ground Shot
Now, it’s time to test the Avanti Precision Ground Shot. This shot is ground to work best in the 499 BB gun, only. But you readers wondered if it would also be more accurate in the C96 BB pistol. To test that theory, I shot another 2 groups of 10 shots each at the same 5 meters. The first group measured 0.954 inches between centers. One BB was outside the black, and 2 more were right on the edge.
The second group I shot with this ammunition measured 0.556 inches between centers. It’s the smallest group of this session and would seem to lend credence to the Precision Ground Shot being more accurate than the Daisy Premium Grade BBs. However, the difference in group sizes of the 2 different BBs is not so great as to be overwhelming. Yes, both groups with Precision Ground Shot are tighter than the corresponding 2 groups made with the Daisy Premium Grade BBs, but the differences are not large. I don’t think they justify shooting the Precision Ground Shot in the pistol since they cost roughly 2.5 times more.
The Avanti shot went slower than the Daisy Premium Grade BBs and also varied more. However, the difference wasn’t much in either category.
The Avanti shot also appears to be slightly more accurate than the Daisy Premium Grade BBs. Again, the difference is very small, but it is there.
I’m surprised by these results. I predicted the Avanti shot would be faster because of its slightly larger size, but that it wouldn’t be any more accurate. So, I was wrong on both counts. I don’t think the difference between the two types of ammunition weighs in favor of using the Avanti shot in this gun, but it’s really a call the owner of the gun needs to make.
My thanks to RidgeRunner and others who asked for this test.

Today, we’ll look at the accuracy of the Legends C96 CO2 BB pistol, and I can sum it up in a single word: Spectacular! Those who like accurate BB pistols will want to put this one on their list.
I shoot all BB guns at 5 meters, which is about 16 feet, 5 inches. While that sounds incredibly close, it is the distance at which the Daisy National BB Gun Championship is shot; and if it’s good enough for the champions, it’s good enough for me. Besides, testing all BB guns at the same distance gives consistent results that can be compared across many tests.
I shot this test with my forearms rested on the back of a wooden chair, and the gun held in 2 hands. That eliminated as much of me as possible, giving the pistol a fair chance to shoot its best.
I used 50-foot smallbore rifle targets whose black bulls are almost 1.5 inches across. At 5 meters, they make perfect aim points for open sights. The C96 has a tapered post front sight and a V-notch in the rear. When the target is illuminated with 500 watts of halogen light, the sight picture becomes sharp and crisp, and sighting can be precise.
Daisy Premium Grade BBs
The first target was shot with Daisy Premium Grade zinc-plated BBs. The very first shot hit at the extreme bottom of the paper target, and I discovered one of the great features of this pistol. It has a tangent rear sight like the firearm it copies, and it was easy to raise the rear notch up just a bit. By sheer luck I got the elevation almost perfect on the first try, so I left the sights alone after that.
The next 9 BBs went into a shockingly small group, so I loaded one more BB into the magazine to make up for the first shot that was low. When I fired it, it was the only Daisy BB to hit outside the black after the sight adjustment. The 10-shot group measures 0.852 inches between centers. I think you’ll agree this is a very nice group of 10 from any BB pistol!
Next up were Crosman Copperhead BBs. They hit the target in the same place as the Daisys, and the 10-shot group measures 0.937 inches, which isn’t much different than what the Daisy BBs did.
Umarex Precision Steel BBs
Finally, I tried the Umarex Precision steel BBs. They rival the Daisys in precision and this time that was evident. Ten of them went into 0.863 inches, with nine of them in a much tighter bunch. Like the other 2 BBs, these also threw a single BB into the white.
Like the Mauser firearm it copies, this BB pistol has no provision for windage adjustments. Both the Mauser firearms I owned shot about a foot to the left at 25 yards, so I’m used to this. Some older pistols have sights that can at least be drifted to the side in dovetails, but not the Mauser. With this gun, you soon learn to apply Kentucky windage to lay your shots where you want them.
But let’s face it, this isn’t a realistic test for a BB pistol. BB gun shooters plink at cans. They don’t shoot groups at paper targets — at least not often. This pistol is easily a minute-of-Coke-can handgun out to 20 yards.
I found 2 things about the trigger pull when conducting this test. The first is that the trigger blade is located too close to the grip. That’s a part of the lack of ergonomics that the Broomhandle family of pistols all share, and there’s nothing to be done for it. This BB pistol is a faithful copy of the firearm, including a less-than-optimum grip.
The second thing I noticed was how hard the 2-stage trigger seemed to pull. Looking back at Part 2, I see that I did not measure the pull, so I got out the electronic gauge and measured it this time. Stage 1 requires between 2 and 3 lbs. to complete, and stage 2 breaks at an average of 7 lbs., 11 ozs. The range went from 7 lbs., 1 oz. to 8 lbs., 3 oz.; and the slower and more deliberate the pull, the greater the force required.
Even with that, though, the pistol is blisteringly accurate. And the blowback is pleasant. It’s nothing like the snapping recoil of a 7.63mm Mauser cartridge. So, there’s a benefit of shooting the BB gun over the firearm.
Umarex has a winner, here. Their Legends airguns are all remarkable guns, and the C96 takes its place among them proudly. Not only is it realistic-looking, it gets an astounding number of shots per CO2 cartridge; and, as we now see, those shots all go to the same place.
Let’s look at the velocity of the Legends C96 CO2 BB pistol. It’s advertised at 380 f.p.s., and we know that it has blowback. So, it’ll be interesting to see just how powerful this pistol really is, as well as how many shots it gets.
The first BB I tested was the Crosman Copperhead. They were tested when the CO2 cartridge was fresh, which boosted their average velocity a few f.p.s. They averaged 402 f.p.s, with a spread from 392 to a high of 409 f.p.s. At the average velocity, Copperheads generated 1.83 foot-pounds of muzzle energy.
I found the magazine very easy to load. Pull the follower all the way down and twist the tab into a slot to lock it back, then the BBs are dropped into a trough where an opening dumps them into the single stack slot in the mag. Release the follower, and the gun is loaded. I found the rated capacity of 19 BBs to be spot-on.
Daisy Premium Grade zinc-plated BBs
Next up were Daisy Premium Grade zinc-plated BBs. I though they might be a little faster than the Copperheads, but they weren’t. They averaged 395 f.p.s., with a low of 386 and a high of 404 f.p.s. At the average velocity they produced 1.77 foot-pounds of muzzle energy.
All the time I was chronographing the gun I was also counting all the shots. I noticed that when you load a new magazine, the first shot will always be a blank. That’s because of how the gun’s feed mechanism works. I did count those shots in the total because they used up gas the same as if a BB had been shot.
Umarex Precision steel BBs
The final BBs I tested were the Umarex Precision steel BBs. They averaged 394 f.p.s. with a low of 385 and a high of 404 f.p.s. That parallels the Daisy BBs pretty close. At the average velocity, these BBs produce 1.76 foot-pounds of energy at the muzzle.
During the chronographing session, I was waiting a minimum of 10-15 seconds between shots to allow the gun to recover from the cooling effects of the gas. But after the 3 test strings were finished, I continued shooting Umarex steel BBs to see how many good shots there are on one CO2 cartridge. I went much faster during this shooting, with less than a second between each shot. I think this is closer to the way most shooters will use the gun.
I kept expecting the pistol to run out of gas at any time, and it kept right on shooting and surprising me. Finally, at shot 103, I chronographed an Umarex BB going out at 336 f.p.s. While that is slower than the recorded average, you have to take into account the fact that I was now firing the pistol very fast and allowing it no time to warm up. So, an unexpected finding was that this pistol doesn’t suffer as much from the cooling of the gas as most CO2 guns. There normally would be at least a 100 f.p.s. velocity drop when shooting this fast.
Finally, after shot 123, the hammer didn’t cock for the first time. I cocked it manually and kept on shooting, but it failed to cock again after a few more shots. The gun was now out of gas. Had I wanted to get more shots from it, all I needed to do was slow down my shooting to allow more time for the gun to warm up. I think the shot count could easily be stretched out to 140-150 shots that way.
So, the pistol shoots a little faster than advertised, and it gets a very respectable number of shots from a CO2 cartridge. That’s 2 big plusses for the gun.
Next on the schedule is accuracy testing. I’m looking forward to that! I have to tell you that this C96 is a very neat CO2 BB pistol. Of course, it isn’t ergonomic, but neither is the C96 firearm it copies. It’s not supposed to fit you well — it’s supposed to look like the real deal, and I think it does that very well.

The PCP built on a Crosman 2100B chassis.
Today is Media Day at the range, and I will be shooting many of the new airguns that will be coming out this year, plus a lot of firearms — I hope. Tomorrow the 2014 SHOT Show starts, and there’s a special first-day report all set for you.
Let’s look at the performance of the $100 PCP that big bore airgun maker Dennis Quackenbush created on a Crosman 2100B chassis. I read some comments about the gun in Part 1. Before we get started, I need to address one of them. Some of you say you want a PCP that operates on 100 psi, so you can run it on your shop compressor. Gentlemen — such an airgun doesn’t exist and cannot exist as you envision it. That is simply not enough pressure to push a pellet to the kind of velocities we want. You can shoot t-shirts into the grandstands with that kind of pressure or perhaps run a pneumatic tube delivery system, but not a pellet gun.
I know that the airguns of old used lower pressure than we use today. They got amazing power from 500 to 800 psi. But they weren’t shooting smallbore caliber pellets. They were shooting .40 to .70 caliber round lead balls and they got them up to 450-600 f.p.s. They did that because the area of the projectile is much larger than a .177 pellet, and also because they used very long barrels (30-36 inches).
You can shoot tennis balls with shop air, but not pellets. I did report on a .25-caliber pellet rifle that worked with 800 psi air, but that’s a lot different than 125 psi air. You can’t pressurize air to 800 psi with a shop compressor. So, we’re going to have to confine our research to what is physically possible. I’m not trying to shut you down for thinking outside the box, but this is a very real physical constraint.
On with the test
Today, we’re looking at the velocity of this rifle with air for both pellets and BBs. Pellets are our principal concern, but I’ll test BBs, as well, since they can be used in this airgun.
Dennis told me what the performance curve looked like, but I’m going to approach this as if I know nothing about this gun. Where do I begin? Well, I may not know much about this particular PCP, but I’ve used enough other PCPs that I’m not completely in the dark. I filled the reservoir to 800 psi, as indicated on the gauge of my carbon fiber tank and then started loading Crosman Premier lite pellets and firing through the chronograph.
Okay, the velocity dropped with every shot, so the valve is not on the power curve, yet. It wants to see more air pressure.
Look at the velocity increase from just an additional 200 psi of pressure! That’s an indication that we’re quite far from the power curve. It took 5 shots before the rifle was shooting as slow as in the first string, so that extra 200 psi really added shots.
A word about the next part of the test is appropriate. The gauge on my tank doesn’t show even divisions of pressure as closely as I would like. Instead of adding another 200 psi, I found myself guessing that I added another 300 psi. If I had a more accurate gauge, I could do this with greater control; but it’s all going to turn out in the end. You’ll see.
4…..did not record (DNR)
This was interesting because there wasn’t such a big increase over 1,000 psi as there had been when going from 800 to 1000, despite adding 300 psi rather than 200 psi. It took just 3 shots for the velocity to become equal to the 1,000 psi string (compare shot 3 from this string to the first shot of the previous string). The extra air pressure isn’t doing as much as it did before.
Okay, look at the first 5 shots in this string. See how little velocity they lose compared to the first shots in previous strings? That’s significant. It means the valve is beginning to operate more efficiently at this pressure level. Dennis told me that when he reached 1,800 psi, the rifle stabilized for him, as well. What we don’t know and cannot know for sure is what pressure either Dennis or I actually used because neither of us has a calibrated pressure gauge. We’re just guessing based on the inexpensive small gauges that come with all pressure tanks. But, whatever the exact numbers are, they’re pretty much in the same ballpark.
We have a PCP that operates at 1,800 psi — or so. But when I say “operate,” it isn’t really operating the way we want a PCP to operate. We want to see a nice string of shots that are fairly consistent — some a little higher and some a little lower, but a nice string where the velocity is stable. We don’t have that yet. What we have is a rifle that wants to operate at this fill pressure but probably needs a number of tweaks to get where we want it to be.
There’s one more thing to do. Dennis and I talked about this, and he said if there’s a weakness in this rifle, it’s at the threads where the air reservoir is threaded to the brass valve. While the reservoir is way overbuilt, those threads are a place where not too much more strain can be applied. Dennis feels that it will be safe to 2,000 psi but not much higher. I agreed with him on that, so I did one last test at 2,000 psi.
Okay, adding 200 extra psi increased velocity significantly, plus it also gave us a greater number of consistent shots. I would call the first 7 shots fairly consistent, and the velocity doesn’t really start to plummet until after shot 9. What this tells me is that the valve return spring is way off. It’s probably too heavy. And Dennis has already criticized the valve itself. It’s a poppet shape (looks like a top hat) instead of a valve with angled sides that mate with an angled valve seat.
Add to that an enlargement of the valve port (through which the air flows) that might help lower the operating pressure, and the new valve would handle the pressure better than this stock one that got pressed into service for which it wasn’t designed.
What about BBs?
Okay, I can’t end without giving you some BB velocities. Since the rifle works so well at an indicated 2,000 psi, I decided to skip all the early stuff and go straight to the string we’re all interested in.
For this test, I used Daisy Premium Grade BBs that I know from measurement are both the largest and also the most consistent steel BBs on the American market. Since steel BBs run 0.171 to 0.173 inches in diameter, they’re considerably smaller than .177-caliber lead pellets, no matter what their packages say. BBs are NOT 4.5mm!
Like the pellets with a 2,000 psi fill, the first several shots with BBs are close to each other and after, perhaps, shot 6 or 7, the spread opens up. Of course, you have to realize that steel BBs going over 800 f.p.s. are extremely dangerous. Lead pellets start to disintegrate at velocities above 600 f.p.s.; and at 800 f.p.s., they almost vaporize when they hit a hard target such as metal. But BBs not only hold together, they absorb the energy of the impact and bounce back at nearly the same velocity. Believe me — you don’t want to be hit by one!
What have we learned?
So far, we know this rifle works but is not a fully functional precharged pneumatic because it does not shoot a string of shots at a steady velocity. However, that doesn’t stop us from proceeding with accuracy testing.
What’s been proven by this test is that the idea of a $100 precharged pneumatic rifle is completely plausible. The needed changes have been pointed out; but as we proceed further, no doubt, other things will be revealed. That’s the way of product development.
Remember this is a testbed — not a production rifle. Also remember the rifle that it was built from. We should expect accuracy to be similar to the Crosman 2100B, which is fully acceptable at this price point. And I’m going to select a string of shots whose velocities are relatively close to each other, so I probably won’t be shooting 10-shot groups.
I’ll need to do some things to the gun before starting the accuracy test, but I’ll tell you about those things in the next report.

It’s accuracy day for the Beretta model 84 FS BB pistol, and some of you have been eagerly awaiting this day! I decided to shoot 3 different BBs in the gun just to give you a general idea of how well it groups.
Because this is a BB gun, the shooting distance was 5 meters, which is 16 feet, 5 inches. I sat backwards on a chair, resting my forearms over the back, so the pistol was fairly steady. I selected a 10-meter rifle target for this session because the smaller bull seemed appropriate for the shorter distance.
After installing the CO2 cartridge and loading the first 10 BBs, I tried to shoot the target and the gun wouldn’t fire! What was wring? I knew this was a double-action-only trigger, and it should have worked. Right?
Wrong! This trigger is not DAO. It only feels like one! It’s really a single-action trigger that requires the hammer to be cocked before it’ll work. You can squeeze the trigger all day and nothing will happen until the hammer is cocked. So, with this little problem out of the way, the test could begin.
Crosman Copperhead BBs
First up were 10 Crosman Copperhead BBs. As I shot, I noted that the pistol was very steady in my rested hands. And the target shows that…I think. Ten Copperheads went into 1.521 inches at 5 meters. But note the 2 holes that are apart from the main group. Eight of those BBs made a group measuring 0.78 inches.
The farthest of the 2 holes that are apart from the main group — the one to the extreme right — was a called flier. My hand twitched to the left as the shot fired. The other one, though, was held just like all the rest.
Daisy Premium Grade BBs
Next I tried 10 Daisy Premium Grade BBs. Like I mentioned in Part 1, they’re top-grade BBs that always deliver the goods. This time, 10 of them went into 1.114 inches. There were no called fliers, and the group is fairly well centered on the bull.
The last BB I tried was the Umarex precision BB — another top-grade BB. Ten of them grouped in 1.28 inches, with 9 going into 0.998 inches. There were no called fliers in this group, either.
As I told you in Part 2, the trigger-pull on this pistol feels very much like a double-action pull. That’s one where the trigger first cocks the hammer before releasing it to fire the gun. It “stacks” or increases in effort significantly toward the end of the pull, like a vintage Colt double-action revolver. Once you learn how to use that, it helps with accuracy. The pistol is actually stabilized before firing.
This little Beretta is a fun BB gun, make no mistake. I found it trouble-free and easy to use. The sights are right on, and there are no quirks in the operation. If you like BB repeaters, this would be one to consider!
