History of airguns

This report covers:

  • Sight-in
  • First group
  • Qiang Yuan Olympic pellets
  • RWS Hobby
  • JSB Exact RS
  • Discussion
  • Summary

You asked me to back up to 25 yards with the Crosman MAR177 and today is the day I do it. It should prove to be an interesting report.


Because I was using the iron sights that came with the rifle, I skipped the sight-in at 12 feet and went straight to 25 yards. My sight-in pellet was the Air Arms Falcon that was so accurate in the test at 10 meters.

The first shot went two inches high at 25 yards. After seeing that I adjusted the rear sight down 5 clicks. I had adjusted it up the other day for photography when I was exploring its adjustability and writing Part 5. read more

Tech Force TF79 Competition Rifle – Part 6

The Tech Force 79 Competition rifle is a lot of value for a very low price.

Before we begin today, I wanted to remind you of the 2nd Annual Airgun Extravaganza in Malvern, Arkansas. It’s being held on Friday and Saturday, April 15 & 16. Contact Seth Rowland for more infomation.

Seth has made a deal with a couple motels. Mention the show and you’ll get a discount:
Comfort Inn Malvern, 501-467-3300: Thurs. $55, Fri. $65
Holiday Inn Malvern, 501-467-8800: Thurs. $85, Fri. $90

Make reservations now because they may fill up since the show’s being held on the same weekend as the Arkansas Derby. I have two tables reserved, and the Lord willing I’ll be there with Mac.

Now, for today’s report. From time to time, I’m asked to verify some facts by testing airguns in a certain way. Reader Victor questioned the accuracy claim for the Tech Force 79 Competition Rifle in the last report, and rightly so. It said the rifle is capable of a 5-shot group measuring 0.08 inches at 10 meters — something that the world’s top 10-meter rifles of today still struggle to achieve. I reckoned that the number had been mistakenly carried over at Compasseco in the past from the Chinese BS-4 target rifle that is a near-perfect copy of the FWB 300. That one really was capable of stunning accuracy. When Pyramyd Air purchased Compasseco, they used that description and this detail was never questioned. Given the large number of products that had to be added to Pyramyd Air’s website, it’s easy to see why not.

However, my struggles with the TF-79 during accuracy testing caused Pyramyd Air’s leadership to examine the rifle more critically, and this past week I was asked to establish a new accuracy figure for the rifle — one that’s realistic. Also, one that we know can be obtained. Since I spent an entire morning testing this rifle again, I darned sure was going to get a blog out of it!

I already had a great target from the RWS R-10 Match Heavy pellets. I showed it to you in the last accuracy report, so it became the group to beat. Remember, I’m testing just one rifle. Others may be more accurate and some may be less accurate, and there’s nothing anyone can do about it. No dealer can give you absolute accuracy information for every rifle with every possible target pellet. It simply takes too long. Even the $3,000 rifles are tested with only one pellet. To do otherwise would add hundreds of dollars to the cost of the gun, and would still be meaningless, since at any time a better pellet could come along.

Lest any of you get on the “machine rest” bandwagon at this point, that’s not how 10-meter guns are tested at any factory. They’re tested by human shooters, shooting off a rest. The one time I actually used a machine rest (a heavy machinist’s vise) was at AirForce, testing the Edge, and the results were no better than if I’d held the rifle myself. So, get off the machine rest/vise kick. It just isn’t done in the real world in the interest of time, and it isn’t necessary.

Having said all that from my bully pulpit, I also must admit that the people who test 10-meter rifles at the factories in Germany and Austria are the closest thing to vices that still have a heartbeat. They get real good at what they do, and you can see it in the tiny groups they send with their rifles. On the other hand, I’m just an average joe. I know how to shoot. When I get in the zone, I can even shoot pretty well. But I’m not the equal of the guys who test Olympic-grade 10-meter rifles for a living.

For this test, I had to get into the zone and stay there throughout the test. And THAT, my friends, is where the value of shooting the Ballard .38-55 centerfire target rifle comes in! You may recall that in my last outing to the range, I discovered the zone for the Ballard, and the last two targets showed it most dramatically. With that experience fresh in my mind, it was easy to get into the zone with the TF-79. I think you’ll see that my results prove it.

The target to beat is the best one I shot in the last test. That was with RWS R-10 Match Heavy pellets and measured 0.244 inches across the centers.

The best group of five pellets at 10 meters with the TF-79 rifle being tested was this group of RWS R 10 Heavy pellets. It measures 0.244 inches across the centers.

Pyramyd Air asked me to do a comprehensive test of H&N target pellets (they’re the U.S. importer). I did test other pellets, as well, but 14 groups of H&N pellets were fired during this test. All pellet head sizes of every pellet used in this test were 4.50mm. While other sizes exist, nearly everything I have on hand has that same head size. The JSB S100 pellet (4.52mm head) that I tested in this rifle in the last test made a poor showing. I’m thinking this may be the best head size for this rifle. That’s just a guess, since there’s simply not enough time to test all of the 50+ tins of target pellets I have on hand.

H&N Finale Match Rifle pellets
First, I tested H&N Finale Match Rifle pellets. I thought they might be the most accurate because of their weight of almost 8.2 grains. The TF79 is a powerful 10-meter rifle and needs (may need?) a heavier pellet to gain consistency.

The best target of the session was the very first one fired! Five H&N Finale Match Rifle pellets went into this group measuring 0.269 inches between centers.

The worst of five targets shot with H&N Finale Match Rifle pellets measures 0.395 inches between centers.

All my guessing turned out to be wrong. The H&N Match Rifle pellet had a wider spread of accuracy than some others. It averages 0. 33825 inches for five groups. That’s not a great showing in light of what was to come.

H&N Finale Pistol Match
H&N Finale Match Pistol pellets were next — and they surprised me.

The best groups of H&N Finale Match Pistol pellets measures 0.296 inches between centers.

The worst target of H&N Finale Match Pistol pellets measures 0.353 inches between centers. read more

Part 4

The Tech Force TF79 Competition rifle is a lot of value for a very low price.

Today is the day of redemption for the Tech Force 79 Competition Rifle. You may recall that in Part 4 I turned in an accuracy test that didn’t exactly stir the masses with its brilliance. In short, it was pretty mediocre for a gun calling itself a competition rifle. I cleaned the barrel and did a few other minor things, but that rifle just didn’t cut it, so it was exchanged for another that I tested for you. And, since I already know how this is going to turn out, I can tell you that this rifle shows what the TF-79 is really capable of.

Good trigger out of the box
On the first rifle, I had to adjust the trigger, so that procedure was turned into Part 2, stretching the report a little. But the current rifle came out of the box with the trigger in a very nice place. Very crisp and repeatable, so I did nothing to it.

Sight adjustments were crisper
I also mentioned that the rear sight on the first rifle had mushy adjustments. The rear sight on this rifle was similarly mushy, but only through the first time it was adjusted. Once the sight had covered the adjustment range, it went back and forth with positive clicks and crispness I could feel. Maybe it’s a good idea to run the adjustment all the way in both directions to clear the mechanism before you try to use the sight.

Let’s go!
Without any fanfare, the rifle was loaded with two CO2 cartridges and readied for shooting. All shooting was done off a rest at 10 meters, and the targets were the official NRA 10-meter targets.

H&N Finale Match Pistol pellets
Sight-in took five shots, and I started with H&N Finale Match Pistol pellets because they seemed right for the rifle. As in the previous report, I shot five-shot groups. I wasn’t too concerned with the pellets hitting the exact center of the bullseye, as long as they were in the black. Once I was in the black, I didn’t adjust the sights for any of the pellets.

Now that is more like it. Five H&N Finale Match Pistol pellets. Group measures 0.379 inches.

RWS R-10 Match Heavy pellets
Next, I tried RWS R-10 Match Heavy pellets. They gave me a super group and turned out to be the best pellet I tried. They have a head size of 4.50mm.

That’s more like it. Five RWS R-10 Match Heavy pellets. Group measures 0.244 inches. This turned out to be the best group in the test.

JSB S-100 Match pellets
After that, I tried some JSB S100 Match pellets. These are hand-sorted by weight at the factory. Pyramyd Air doesn’t stock them at the present time, but I have found them to be superb in some target rifles. They have a head size of 4.52mm.

Five JSB S100 Match pellets were disappointing. The group measures 0.438 inches.

RWS Hobby pellets
RWS Hobby pellets were next. You may remember that they were the most accurate pellets in the first rifle. In this rifle, they didn’t do as well, and that’s why we have to test every airgun with every pellet before knowing how it’s going to perform. read more

Tech Force TF79 Competition Rifle – Part 4

by B.B. Pelletier

Before I start, I have 2 announcements:

First, the January podcast is now available. My voice comes and goes, so I have to wait for it to be loud enough to produce the podcasts.

Second, the instructional video section of Airgun Academy has been filling up. I haven’t announced on the blog all the videos as they’ve been uploaded, but we’re already up to No. 18! Also, Pyramyd Air put the first 10 videos on a DVD so you can watch them on your TV or when you’re offline. Of course, you can still access them on Airgun Academy.

Part 3

The Tech Force TF79 Competition rifle is a lot of value for a very low price.

Today, we’ll look at the accuracy of the .177 caliber Tech Force TF79 Competition rifle. This is Part 4 and not Part 3 because of the special report I did on the trigger in Part 2.

The trigger that I reported was doing very well in Part 3 is still performing up to spec for this test. Apparently, the moly took care of the tiny bit of creep left in the sear, so now the trigger breaks crisply. It feels like the target trigger that it is.

There were no called fliers in this entire test. The TF79 shoots so smoothly that the bullseye remains pretty much centered in the front sight aperture element. All shooting was done from a rest at 10 meters. I used both the artillery hold and the rifle rested directly on the sandbag, which you can get away with when shooting either gas or pneumatic recoilless rifles.

RWS Hobbys
I sighted-in the rifle using RWS Hobby pellets. The sights were way off target and had to be adjusted over one inch in both directions. That took a lot of clicks, because each one moves the sight only a very short distance. The clicks are vague and indefinite, but I could feel each one. Some felt soft and mushy, while others felt like the mechanism was binding then releasing.

RWS Hobbys were used to sight-in the rifle. After that, the sights were not adjusted for the other pellets. These 5 Hobbys gave a good group of 0.338 inches.

H&N Finale Match Pistol
The next pellet tested was the H&N Finale Match Pistol pellets. Four of those grouped in a tight 0.29-inch group, but the fifth pellet opened the group to 0.587 inches. That makes me want to try these pellets again, in the hopes that the stray shot was a fluke. But, the sights were set perfectly for all shots and no alibi is claimed. This pellet has a head size of 4.50mm.

A tantalizing group. Four were under one-third-inch, but the fifth opened the group to more than a half-inch. H&N Finale Match Pistol pellets.

RWS R10 Match Heavies
RWS R10 Match Heavy pellets were next, and I really had high hopes for them. But they went the other way, giving one of the worst groups of the test. Five pellets grouped in 0.889″. Another 4.50mm-head pellet.

A disappointing group, to say the least! Five RWS R10 Heavies made this 0.889-inch group.

RWS R10 Match Pistol
If the heavy R10s were disappointing, the lighter RWS Match Pistol pellets were a shock. They produced the second-worst target of the test, with five shots grouping in 1.133 inches at 10 meters. Head size is 4.50mm.

Five H&N Match Pistol pellets made this 1.133-inch group at 10 meters. No need to point out how poor this is, but let’s learn something from it. Compare this group to the one made by the RWS Hobbys, and you’ll see how dramatic a change of pellet can be. read more

Tech Force TF79 Competition Rifle – Part 3

Part 2

The Tech Force 79 Competition rifle is a lot of value for a very low price.

Well, the best laid plans of mice and men….I was supposed to be at the SHOT Show today, but the night before my flight left I went to the emergency room with what I thought might be appendicitis. It turned out to be a small but painful hernia, which cancelled all travel plans and heavy lifting for a while. So, no SHOT Show this year! Apparently, my extended hospital stays and being fed intravenously for so many months last year resulted in too much muscle loss. The doctors believe it will heal up shortly without any surgery.

That’s sad, because Crosman is unveiling a brand new kind of big bore air rifle. Named the Rogue, we called it the electronic PCP during development, because it uses computer control of the valve to get far greater efficiency than has ever been possible.

The idea of an electronically controlled valve isn’t new. Daystate has been doing it for several years and getting great results. But, no other airgun will get the performance this new gun offers. The computer senses the remaining air pressure in the reservoir and holds the firing valve open long enough to extract highly consistent velocities. Instead of 2 shots or 6 good shots from a big bore, what would you say to the possibility of 10 high-powered shots? Or, change the programming and get 20 lower-powered shots at a level that’s still impressive.

This new system was invented by one of our own blog readers, Lloyd Sikes. He signs in here as Lloyd. He first showed me his design at the Roanoke airgun show several years ago, and I was so blown away with the possibilities that I set up a meeting with Crosman. Of all the airgun companies in the world, Crosman is the only one open to new and radical ideas, as well as having the engineering and production capability to act on it. Lloyd initially demonstrated his invention by video, followed by several live demonstrations at the Crosman plant. They made the decision to take his idea and make it into a producible airgun system, and I use the word system advisedly. Although the initial offering is a rifle in .357 caliber (imagine the hundreds of lead bullets now made in this caliber!), a barrel change allows conversion to .30 caliber and even .410 gauge! For the first time in history, we may have an air shotgun with power identical to a firearm! I’m talking about sending a half-ounce of shot out the muzzle at over 1,100 f.p.s.!

Imagine filling to 3,000 psi and still firing shots at the same velocity when the pressure has dropped below 1,500 psi. This will be the most flexible, most adaptable big bore airgun ever conceived.

Crosman has poured their corporate heart and soul into this project, knowing that they have a technology unlike any that’s gone before. The future may hold .50 caliber buffalo rifles, real usable shotguns, smallbore rifles that have incredible velocity uniformity…and the list goes right on out to the horizon. And, you, my dear readers, are the absolute first set of airgunners outside the development team to learn about it. This is the big bore that many people guessed would be some kind of Marauder on steroids. It’s nothing of the kind. It’s a brand-new technology that has never been seen before.

I’ll be getting a rifle to test for you this year, so the future bodes well for more great new toys.

Today, we’ll look at the velocity of our .177 caliber Tech Force Competition Rifle, as well as the endurance of two 12-gram CO2 cartridges. Don’t be confused because this is Part 3. I did a special report on the trigger in Part 2.

Pyramyd Air rates this target rifle at 550 f.p.s., which is right where a 10-meter target rifle ought to be. But, the test rifle proved to be more powerful than that. Before I get into the velocity numbers, though, I’d like to share some more info on the trigger.

Sweet trigger
At the end of the trigger report in part 2, I told you that the trigger was almost creep-free. Just a hint of creep remained in stage two because I insisted on more sear contact area for safety. I also lubed the sear and the trigger contact with moly grease. Within just a handful of shots, the moly had erased all hint of creep, and I now have a target trigger worthy of the name. I cannot emphasize too strongly what an incredible value this trigger is in such a low-priced airgun.

The first pellet I tested was the RWS R10 7.7-grain target wadcutter. It seems RWS has dropped this pellet in favor of an even lighter 7.0-grain R10. But, it was the heavier pellet that I tested. They averaged 613 f.p.s. and the range stretched from 608 to 617 f.p.s. for a span of 9 f.p.s. They average 6.43 foot-pounds of muzzle energy.

Next, I tried the H&N Finale Match Pistol pellets. They weigh 7.56 grains and they averaged 617 f.p.s. in the test rifle. The range went from 614 to 619 f.p.s., so a tight spread of only 5 f.p.s. The average muzzle energy was 6.39 foot-pounds.

I cannot emphasize too strongly what an incredible value this trigger is in such a low-priced airgun.

Gamo Match pellets were next. They weigh 7.71 grains and averaged 613 f.p.s. in the test rifle. The velocity spread went from 610 to 617 f.p.s., so only a 7 f.p.s. spread. Average muzzle energy was 6.43 foot-pounds.

The last pellet I tested was the RWS Hobby. They were the fastest pellets, at an average of 632 f.p.s., and the range went from 629 to 636 f.p.s. The spread was 7 f.p.s. The average muzzle energy was 6.21 foot-pounds.

After this testing, a total of 40 shots had been fired with the two CO2 cartridges. I continued shooting Hobbys to see what the total number of shots would be. The velocity fell off immediately. By shot 48, it dipped below 600 f.p.s for the first time. This particular rifle has a total of 40 good shots on a set of two CO2 cartridges. That might be extended a few rounds in the hot summertime, and in cold weather it might be a few less. I shot in my office with the temperature at 70 degrees F.

A plinker could go on for several additional shots, but a target shooter wouldn’t want to. That’s where the degasser comes into play. When CO2 is in the reservoir, the o-rings press against the walls of the reservoir so hard that no amount of effort short of vice grips can turn the end cap off the gun. The degasser lets you dump the remaining pressure and start all over again.

The degasser slips into a hole on the left side of the gun and works just as the name says.

I’m going to get a setup for bulk-filling in a future report. For now, know that the TF79 is even more efficient than the classic Crosman 167 (the .177 caliber version of the 160). Coupled with better overall design and a finer trigger, that’s saying a lot. Accuracy will be the next thing we look at.

Tech Force TF79 Competition Rifle – Part 2

by B.B. Pelletier

Part 1

The Tech Force 79 Competition rifle is a lot of value for a very low price.

Today, we’ll look at the trigger of the .177 caliber Tech Force TF79 Competition Rifle, which I promised would get a report all its own. Back before the QB 78/79 rifles came to market and back when I was still reporting on the original Crosman 160s, I discovered that there were different variations of the model that came with different triggers. The first 160 made back in the 1950s had a dirt-simple, direct-release, sear-type trigger that had no special advantages. This was the rifle that had a crossbolt safety through the stock. Back then and probably still today, those rifles commanded less money than the later models that have the trigger I’m going to discuss today.

In fact, this trigger I’m discussing today was the cover subject of the premiere issue of my newsletter, The Airgun Letter, published in March 1994. So, for those folks who wonder if I’ve ever looked at the TF79 before now: I have been looking intently at both it and its direct ancestor for the past 17 years, which is my entire airgun writing career.

The first article in the first issue of The Airgun Letter was about the adjustable trigger in a Crosman 160.

Back in 1994, I was just learning how to take pictures with a 35mm film camera, and it would be more than a year before I started having much success. When it came to capturing the inside of the trigger, I didn’t photograph it, I drew it! It took about four hours to complete the drawing, but I’ve used it many times since.

Before I could take good pictures, I drew things to illustrate them. This is my drawing of the 160 adjustable trigger. The only difference between this trigger and the one we’re reviewing today are two tiny coiled springs that put side tension on the two trigger-adjustment screws. Today, things are simpler and better. read more

The Tech Force 79 Competition rifle is a lot of value for a very low price.

If you’re new to airgunning, you need to know what transpired to bring a rifle like the .177 caliber Tech Force TF79 Competition Rifle to the market. It began in the 1950s with the inception of the Crosman 160. The 160 was a .22 caliber single-shot CO2 rifle that used two cartridges to shoot 25-35 pellets at around 610 f.p.s. Back in the 1950s, the 160 was a minute-of-Oreo-cookie at 15 yards. As time passed and European pellets began arriving at our shores, the accuracy improved. The Crosman barrel was always well-rifled, but it took us several decades to realize how good it really was.

Crosman also improved the rifle, ultimately resulting in the high-water mark, which was a military single-shot target rifle with a Williams S331 peep sight and a genuine leather sling. I was active as an airgunner in Maryland in the 1990s when several hundred of these Crosman Air Force rifles were discovered in a warehouse and sold as new old stock. For a while, I owned a brand new 1980 Crosman MIL-SPEC target air rifle.

However, in the 1990s, the Crosman Premier pellet was available. So, the rifle that the Air Force thought might shoot a half-inch five-shot group at 25 feet was suddenly capable of shooting just as good at 25 YARDS. The pellet made all the difference in the world; and, for many years, the airgun world was hot for 160s.

Enter Tim McMurray and Henry Harn. Tim we all know as Mac-1, and he’d been working on 160s for decades by this time. Harn was a businessman with connections in China, so he asked Tim to put together the finest version of a 160 he could, and then Harn would have the Chinese duplicate it. Yeah, I know what you’re thinking, only Harn and McMurray rode the Chinese roughshod until they got what they were after — more or less. The QB-22 was a knockoff of the Crosman 160 that gave nothing away in quality or accuracy. Tim did have early problems with barrel quality, but he sorted it out.

But, the QB-22 retailed for $200 in the 1990s. Like today, everyone wanted a free lunch, so the guns didn’t move as fast as expected. If you build it, they won’t necessarily come, but a lot of them will stand around with their hands thrust deep into their empty pockets and kicking dirt clods while saying things like, “What they should have done….”

The QB 22 languished. About a year later, something called a QB 78 hit our shores and it retailed for about $78. That got people talking. A real Crosman 160 for $78! Only, it wasn’t a real 160, of course. It was a gamble. Some of them shot great, while others were just mediocre. For the first time, the Chinese were embarrassed by their own lack of quality. They had expected huge sales, but the lackluster performance of the gun left sales in the dumper. Apparently, you can’t just build a mock landing strip and control tower to attract the cargo planes from the U.S. (I’m referring to the cargo cults.)

So, they did something remarkable. They built a new and improved rifle — the QB 79. The gun they should have built all along, only they didn’t. Now, they were at it full bore. Yes, the QB 79 was the gun you really wanted, but they had quality problems with that model, as well. Some were great shooters, while others were only mediocre.

Okay, now I have to hit the fast-forward button, because both these designs have matured and morphed like gangbusters in the past 10 years. For example, there’s a target version of the QB/TF 79 that’s a super deal in an accurate single-shot. Compasseco had a TF78 with a dark stock and a gold trigger that was to die for. Whole cottage industries have sprung up around these models. Mike Stephen (sorry for the typo!) Archer in upstate New York makes his living selling both repair parts and modified parts for the rifle and by selling high-graded rifles, which are based on accuracy.

That’s enough history. You now know that what we’re about to look at is a close copy and descendant of the famous Crosman 160. You may not yet know what that entails, but therein lies my report.

The rifle I’ll be testing for you is the full-blown TF79 target rifle. It comes with both a precision adjustable aperture rear sight for 10-meter work and a sporting sight that lets you use the rifle as a plinker. You also get two inserts for the target globe front sight. The ring insert comes installed, and there’s also a post insert for the sporting rear sight. Anyone who wants to put the little holes in the center of the target will use the ring insert and aperture rear sight.

With the rifle comes a large metal precision aperture target rear sight. While not the equal of a $500 European target sight, it works. There’s also an adjustable sporting rear sight, if you chose to use it.

The steel receiver is topped with an aluminum dovetail base for the rear peep sight or sport sight. This same base will also accept an 11mm scope mount, and I know that a lot of you are going to be putting scopes on your guns. The lack of recoil means you have nothing to worry about as far as anchoring the scope rings.

Charging the gun
This rifle operates either on two CO2 cartridges or via a bulk-fill adapter. However, the bulk-fill CO2 hose and paintball adapter was left out of the box I received. I think I’ll simply use CO2 cartridges to test the gun, anyway. With the hose, it’s possible to bulk-fill the gun from a standard paintball tank.

Replace the reservoir cap with this adapter cap, and the CO2 hose screws into the end of the adapter. The hose was missing from my box, so I’ll just use CO2 cartridges.

Just screw a paintball tank into the adapter, and you’re ready to fill the rifle with bulk CO2.

You also get two Allen wrenches for making adjustments, and there’s a degasser that Crosman never thought of. The degasser allows competitors to dump their partial fills and start a match with a full tank of CO2, something that cannot be over-estimated. Degassing also acts to chill the reservoir, to enable a denser fill when bulk-filling.

In all, you get about the same amount of support gear as comes with a $2,000 10-meter air pistol. I’m very impressed at this well-thought-out package for just $180. And, let’s get that out of the way right now. Carp all you want, there simply are no other 10-meter target rifles that sell for this price. Even used, you’ll be hard-pressed to find anything.

The rest of the accessories are the sporting rear sight, the front sight post insert and the two Allen wrenches for adjustments. The degasser lever fits into the left side of the receiver when you’re ready to exhaust some gas. read more
