The Cometas Lynx V10 is an exciting precharged repeater.
Before I start, here’s a reminder that the Roanoke Airgun Expo will be held on Friday and Saturday, October 19 and 20. If you can come, try to arrive on Friday (noon to 7 p.m.), because that’s when the best deals are found — though there can be some good local walk-ins on Saturday. They say the show goes 9 a.m. to 4 p.m. on Saturday, but don’t believe it. By 1:30 the place starts clearing out fast.
The location is in the Roanoke Moose Lodge #284 at 3233 Catawba Valley Drive in Salem, VA, but don’t expect to find it with Map Quest. Just drive up Catawba Valley Drive (which is on Map Quest) several miles until you see the Moose Lodge on a hill on your right.
Mac and I will have a couple tables there. Mac’s bringing a couple 10-meter guns, and I’m bringing that cased FWB 124 I wrote about. Other dealers like Larry Hannusch will be there, and you never know what you will find at this show. Several of our regular blog readers such Fred from the PRoNJ and RidgeRunner will also be there. If you’re a blog reader, please stop by my table and say hi. Okay, let’s get to today’s report.
Today, I’ll show you the results of shooting the Cometa Lynx precharged air rifle at 50 yards. This is the real acid test for any air rifle — precharged or otherwise. They may hold together well out to 35 and even to 40 yards, but I’ve found from long experience that 50 yards separates the good ones from the great ones. And it exposes the ones that can’t keep up.
And here’s an important reminder for newer readers. I shoot 10-shot groups unless there’s a good reason not to. I always tell you if I’m shooting less than 10 shots. Five-shot groups simply do not test a rifle’s accuracy. What they test are the laws of chance, a shooter’s hopes and a bunch of other things that aren’t important, but 10-shot groups prove the real accuracy of the airgun.
My groups will always be larger than those you see elsewhere. Ten shots will group larger than 5 shots in so many cases that it isn’t worth thinking about. Whenever I go back and read these reports to find out the accuracy of an airgun I’ve tested, I’m so glad when I tested it with 10 shots and disappointed if I tested it with less. I hate the additional work it entails, because every one of those shots has to be perfect, but the result is well worth the effort.
News from AirForce
The day before I went to the range last week to test this rifle, I got a call from John McCaslin of AirForce. He told me they’ve been testing all the Lynx rifles and they found that dialing the power back to 20 foot-pounds produced better results for them. You’ll recall from Part 2 that our Lynx is putting out pellets at close to or just over 30 foot-pounds. So, based on that information, I went to the range with the power dialed back to about 20 foot-pounds.
I did that over the chronograph the day before going to the range. There were two pellets that John told me were giving him good results — the 15.9-grain JSB Exact pellet that had not done so well for me at 25 yards and the 18.1-grain JSB Exact Jumbo Heavy that was the best pellet in my 25-yard test.
John told me to adjust the velocity until the 15.9-grain JSB was going about 750 f.p.s., so that’s what I did. It took 2 complete turns of the power adjustment screw to get it to that velocity, where it produces 19.86 foot-pounds, and I nailed that average.
The Allen screw atop the rear of the receiver (in the upper right corner of the photo) is loosened so the power adjustment screw can be turned. I had to remove the scope to loosen the top screw, so I left it loose for adjustments at the range. The position of the Allen wrench leg tells you where the adjustment has been moved relative to where you began.
To adjust the power, loosen the locking screw atop the rear of the receiver, so the power adjustment screw will turn. I had to remove the scope to get at this screw; but if I owned this Lynx, I’d cut the short leg off an Allen wrench for this job. Then the scope could remain in place.
Since I was going to the 50-yard range and the 4.5-14×42 Hawke Tactical Sidewinder scope was available, I installed it at this time. It’s the clearest scope I have, and I wanted to give the Lynx every opportunity to shine.
I get to the range very early to avoid the wind that always picks up in this part of the country. Unfortunately, on this perfectly calm day, there was another shooter already there and he was one of those super-gregarious types who likes to tell you his life’s story in 30 minutes or more (per anecdote!), so I had to be a little rude. If I’m not done shooting by 9 a.m., I’m out of time because the breeze almost always kicks up. I also had the Rogue to test on this day, but I tested the Lynx first because the Rogue’s bullets are heavy enough to buck a little breeze.
The first pellet I tested was the 15.9-grain JSB. Unfortunately, the test rifle still did not like it, even at 20 foot pounds, so I stopped the group after just 6 shots. The group was already at 1.871 inches, and I didn’t see any future in it. As I said, I was burning sunlight fast and trying to pull away from Gabby the Gunman on the next bench, so I shifted to the 18.1-grain pellets next. We were the only two shooters at the entire range complex and, with a dozen benches on the 50/100-yard line, he had to sit right next to me and shoot his short-barreled Remington 600 in .308! The blast reminded me of tank gunnery!
While it sounds like I’m rushing, I’m actually taking a lot of time with each shot. I’m just moving as fast as possible for everything besides shooting. But with 10-shot groups, it’s vital that no shot can be called a flyer. Because if it can, you have to shoot the group over again.
The 18.1-grain pellet was much better at 50 yards, though the final shot did open the group quite a bit. But it was a perfect shot on my end — that was just where the pellet went. Ten shots went into a group measuring 1.756 inches, but 9 of them went into 1.005 inches. And this was on low power, with this pellet going about 710 f.p.s. The breeze was just beginning to kick up, so I adjusted back to high power and shot another group.
You might wonder how I adjusted power at the range. I didn’t have to use a chronograph, because the day before I’d discovered that the Lynx will return to a certain power level based on how far the screw is turned. All you have to do is watch the short end of the Allen wrench and use it as an indicator. I knew that two complete turns of the screw would put me back where I wanted to be, so it was that simple.
On high power, 10 shots went into 1.47 inches, but 9 of them went into 1.108 inches and 8 made a group that measures just 0.928 inches between centers. See what I mean about 10-shot groups? I shot only a couple of them, and yet I got data as good as a handful of 5-shots groups. Because with a 5-shot group, you never know….
The breeze was starting to pick up, and I needed to get on with the Rogue test, so there was time for just one more pellet — the big 25.4-grain JSB Exact Jumbo Monster. It had shown promise at 25 yards, so I wondered how it would translate to 50 yards. The gun was still at 30 foot-pounds, so the power should be fine. Even at this level, this heavy pellet only goes 741 f.p.s. But this one did not want to group at 50 yards! The pellets were shooting such a large open group that I didn’t even bother completing it. And I can’t show it to you because several shots were off the target paper (but still visible on the paper backer I always use).
So my test shows that the Lynx seems to group 10 good pellets into just over one inch at 50 yards. That’s good, but it has a lot of competition at the same price or better.
The Lynx has a regulator, so it gets more shots than unregulated guns shooting at the same power. When it’s on the reg, those shots are very consistent. It has both a magazine and a single-shot adapter, so you can be satisfied either way.
Although several readers did not like the appearance of the wood stock, I like it. The work seems on par with any other high-end PCP stock. I also liked the standard Foster quick-disconnect fill fitting. And the shroud certainly works well, as the rifle never hints at the power it produces — it sounds like a .22-caliber Diana 27 springer running at 475 f.p.s.
I expect the accuracy will be the biggest sticking point for most people. With the Talon SS, Condor and Marauder on the market — all of which can produce smaller groups at 50 yards under perfect conditions — a fellow would really have to love the Lynx. He might like it because, unlike the AirForce rifles, it has a wood stock, or unlike the Marauder, the stock is slim and trim. Either way, now you know the whole story.

The Cometas Lynx V10 is an exciting precharged repeater.
Today, we’ll look at the accuracy of the Cometa Lynx V10 precharged air rifle for the first time. This test will be at 25 yards and will give me the opportunity to adjust the scope and to find one or two accurate pellets for this rifle. I also plan to shoot the Lynx at 50 yards, so today is preparation for that.
I used the single-shot adapter for all shooting in this test. I’ve used the magazine for this rifle and it works fine; but when I’m doing accuracy tests, I like to shoot them one at a time, if possible.
The test was 10 shots, rested, at 25 yards, unless otherwise stated. The first pellet I tried was the 15.9-grain JSB Exact pellet. I’d thought this might be the most accurate pellet in this rifle, as it often is in PCPs of this power. But this time was different, for 10 pellets made a group that measures 0.795 inches between centers! That’s not a good group for a PCP at 25 yards. It’s more of a magnum-springer group.
That target surprised me, for I thought this pellet would be a slam-dunk, and it clearly wasn’t. That caused me to slow down and think about the test a little more.
The next pellet I tried was the Beeman Kodiak. I had played with Kodiaks earlier in this rifle, and they seemed to do well. This time, though, they didn’t group at all. I stopped shooting after 5 shots, and that very vertical group measures 0.879 inches between centers. I did notice that the pellets fit very tight in the breech, so that may be the problem.
At this point, there was nothing to lose, so I tried the Predator Polymag pellet. It has never performed well for me in the past, but I thought this time might be different. Alas, that wasn’t the case. I lost the count and shot 6 Predators into a 0.731-inch group. That’s too bad, because if you can hit with this pellet it does perform. But with accuracy like the Lynx is giving, you’re taking too big a risk when shooting at any distance.
I switched to that old-time favorite, the Crosman Premier. These are usually good in PCPs. But in the Lynx, just 5 of them gave a horizontal group that measures 0.781 inches between centers. Another non-starter! And those who like to analyze things might consider how the rifle can string Kodiaks vertically and Premiers horizontally.
Finally, the pellets were found!
I was very concerned at this point. The rifle wasn’t liking any of the pellets I usually select for accuracy. But there were a couple good choices remaining. The first of these was the 25.4-grain JSB Exact Jumbo Monster, a new domed pellet that delivers a huge punch in a precharged rifle. This was the first time I think I’ve tried this pellet in a test, though the tin was already open when I started. And they grouped well in the Lynx, too! Ten made a tight group that measures 0.492 inches, and that’s with a single straggler! Nine went into 0.464 inches!
The next pellet I tried was the JSB Exact Jumbo Heavy — an 18.1-grain dome that some readers really admire! I haven’t gotten the best results from this pellet in the past, but this time I did. Ten went into a group measuring 0.362 inches. It was the best group of the session, and the one I will shoot first at 50 yards!
I learned a lot from this test. First, I learned that accuracy isn’t always a given. You have to try other pellets to find what works. And when you find it, the difference in accuracy can be startling.
Next, I learned that how the pellets feed into the breech may have a lot to do with the ultimate accuracy. I was certainly able to feel when the Kodiaks weren’t working.
Next stop is the 50-yard outdoor range, where the Lynx will be up against the odds. Ten shots at 50 yards is a pretty good acid test of accuracy for any airgun.

Today, we’ll look at the velocity and power of the Cometa Lynx V10 precharged air rifle. Blog reader /Dave has asked if I will please post the price of the gun in the first report because he reads the blog on his telephone, where navigation is difficult. I didn’t do that in part 1…but it lists for $950 at PyramydAir.com.
This will be a learning day, because the Lynx has a regulator. A regulator controls the air pressure and volume that’s available to the firing valve, so each shot gets almost exactly the same volume of air. That has two benefits — one obvious and the other subtle.
The obvious benefit is greater shot-to-shot consistency. On some air rifles, this can be as small as one or two foot-seconds across the entire usable fill, but that usually happens with lower-powered guns. Higher-powered guns may vary more, but they’ll still be relatively close.
While some unregulated guns get 10-shot strings with very close velocities — when you look at the entire fill, they can vary by hundreds of f.p.s. So, the second benefit is that you’ll get the same velocity throughout the entire part of the fill where the regulator is “on.” We saw that most recently when I shot the Talon SS with the Micro-Meter tank.
How the regulator works
The regulator is set to allow only a certain amount of air into the firing chamber. This is done by air pressure. When the firing chamber has the allotted pressure of air, it closes the reg so no more air can flow from the reservoir. As long as the pressure in the reg remains higher than the firing pressure, the gun will shoot very consistently. The firing valve is tuned to operate best on very low air pressure.
Falling off the reg
When the pressure remaining in the reservoir is not as great as the regulator’s adjusted pressure, the regulator stops working. We use the term “falling off the reg” when this happens. It’s very sudden and can be spotted immediately by a shooter with experience. From that shot on, all shots will diminish in power, though they may still retain enough power to be useful for quite a few more shots.
I’m not just interested in the power of the Lynx, but also the point it falls off the reg, as that determines the maximum number of useful shots you get from a fill. I’m also interested in how closely the onboard pressure gauge correlates with the regulator. In other words: Can I trust the needle on the gauge?
I selected three pellets to test today, because they’re the three I’ll choose for the accuracy test. I may use one or two other pellets later on, but these three will give us a good idea of the Lynx’s performance.
JSB Exact 15.9 grain
The Lynx I’m testing is in .22 caliber, so I selected the JSB Exact 15.9-grain pellet to test first. I did so because this has proven to be the most accurate pellet in the majority of PCPs I’ve tested in .22 caliber. The gun was filled to 3,000 psi and shooting commenced.
The first shot went 923 f.p.s. After that, nothing went faster than 916 f.p.s. with this pellet. That first shot was needed to wake up the reg and the valve. I disregarded it for this test, except that I counted it in the total number 0f shots per fill. It was probably unnecessary to disregard it, as the velocity didn’t change that much; but with other guns I’ve tested, it does. This has become a habit for me.
The first string of 10 shots (discounting the very first shot) averaged 912 f.p.s. The string ranged from a low of 906 f.p.s. to a high of 916 f.p.s., so 10 foot-seconds was the total spread. At the average velocity, this pellet generated 29.37 foot-pounds of energy at the muzzle.
Next up were 14.3-grain Crosman Premiers. They averaged 947 f.p.s. and had a spread from 939 to 953 f.p.s. That’s a 14 f.p.s. spread. At the average velocity, these pellets generated 28.48 foot-pounds, or just slightly less than the heavier JSBs. That’s what you would expect in a PCP, as they usually become more efficient with heavier pellets.
I expect Premiers to be accurate in the Lynx, but probably not quite as good as the JSBs. On the other hand, there’s another pellet that may challenge the JSB for the top spot. That pellet is the Beeman Kodiak.
Beeman Kodiak pellets are made by H&N. They’ve varied in weight over the past several years, so I weighed the pellets from the tin I was using in this test. These pellets averaged 21.1 grains. They averaged 825 f.p.s. in the Lynx with a spread that went from 821 to 829 f.p.s. They varied by only 8 foot-seconds across the entire string. At the average muzzle velocity, they produced 30.9 foot-pounds of energy. This may be the pellet to watch for accuracy.
After the Kodiak string, the rifle had fired a total of 31 shots since being filled. The needle was still in the green zone, so I ran another 10 JSB Exacts through the chronograph. This time, the average was 908 f.p.s., with a spread from 905 to 913 f.p.s. The rifle was still on the reg after 41 shots.
The needle on the gauge was now down close to the bottom edge of the green sector. But I kept on shooting to see what the total shot count would be before the gun fell off the reg.
The next shots registered as follows.
49………..904 (Gun fell off the reg)
The Lynx I’m testing gets about 50 good shots per fill. Those shots are all around the 30 foot-pound range when medium-heavy pellets are used.
The Lynx is very quiet for its power. This is a rifle that won’t bother most neighbors, unless they are laying in wait for you.
The trigger is different because the first-stage pull has a lot of the weight in it. It takes some getting used to the rifle to feel stage two, but once you do it’s very positive. Stage two is totally free from creep, and there isn’t any travel after the release.
The first stage takes 2 lbs., 4 oz., then stage two breaks at 3 lbs., 5 oz. as the adjustment is set from the factory. I fiddled with the two screws that seem to affect the adjustment, but I didn’t get anywhere. One of them simply loosened the push-button safety, while the other introduced a third stage to the pull without affecting anything else. But the trigger is already very nice, so this wasn’t a problem.
Accuracy is next, and I’ve decided to divide it into two parts. First, I’ll sight-in at 25 yards and find the best pellet. Then, I’ll go out to 50 yards and see what this rifle can do. This should be an interesting test.

Oh boy! Another new precharged air rifle to test! This one is called the Lynx V10 and is made by the Spanish firm of Cometaand distributed in the U.S. through AirForce International. Instead of offering these guns through AirForce Airguns, the company has elected to create a separate entity called AirForce International that will sell all the products that are not made in the United States. The Cometa line launches this endeavor.
The Lynx V10 has been seen in the U.S. previously but was represented by smaller dealers who sold whatever configuration the company made. AirForce International has requested specific standard specifications for the guns they sell, and they will have other exciting changes to announce in the future.
The rifle I’m testing for you today is the Lynx V10 — a .22-caliber 13-shot sidelever repeating precharged rifle. It takes a conventional 3,000 psi/206 bar fill of air in the 290cc reservoir. Although the reservoir appears to be removable, it can be left in place on the gun and filled through a standard male Foster-type filling in the bottom of the stock.
I’m testing serial number 30638-11, but you won’t be able to buy this one because I’ll have to return it to AirForce International, who supplied it for this test. They sent the rifle mounted with an AirForce 3-9×40 AO scope, so that’s how I’ll test it. I have both the single-shot adapter and a 13-shot magazine, so I’ll test both for you.
According to the AirForce International website, the rifle will deliver velocity from 700 to 1,000 f.p.s., depending on the weight of the pellet. So, I’m expecting power to be in the 30+ foot-pound region.
The rifle I’m testing is mounted in a natural wood finish stock. The test rifle stock has a pleasing grain pattern and appears to be walnut, though the specifications do not list it. Other stock finishes of blue and black are available.
The rifle weighs 9.5 lbs. as tested, with the scope mounted and single-shot adapter installed. The advertised weight of just the rifle alone is 7.8 lbs.
It is 41.3 inches in length and has a pull length of just under 15-1/2 inches. That pull may be too long for many shooters. I find it very comfortable, but I do like a longer pull. The black rubber buttpad adds an inch to the stock. If you need to trim the pull, that’s the place to start.
The stock is completely ambidextrous, and only the sidelever on the right side of the receiver and the fact that the single-shot adapter swings out to the right for loading shows any bias whatsoever. The comb has a very tall and sharp Monte Carlo profile, and the cheekpiece is subtly raised on both sides of the butt. Both sides of the grip and forearm are covered with attractive checkering.
The forearm is quite wide, while the butt is surprisingly narrow in cross-section. The forearm, though, has to house the back part of the air reservoir, so the wide forearm does not add any weight to the gun. The resulting feel of the rifle is that it’s large but not overly heavy — at least so far. The pressure gauge is inset into the left side of the forearm, where it’s easy to read.
The barrel is shrouded and has a bull-barrel look. I’ll report on the sound at firing after I’ve tested it indoors for velocity, and perhaps again after accuracy testing outdoors. The fat shroud should be able to do an effective job. While the test rifle does not contain any baffles, there’s a large collection chamber in front of the true muzzle — not unlike what’s found in the production Talon SS.
The trigger is two-stage and adjustable for pull weight. The one on the test rifle seems to be adjusted perfectly. I plan to leave it alone until I shoot the rifle for accuracy, because it’s right where I want it. Stage one has some weight to it, and stage two breaks glass-crisp.
This is a sophisticated PCP, make no mistake. The reservoir is regulated, and the power is adjustable. I’ll explore the latter after accuracy testing, but the former will come to the forefront when I report the shot count. Many of you have asked about the utility of a regulator — well this rifle has one and now we’ll see how well it works.
So, yes, the Lynx V10 is pricey, but before we close our minds, let’s see what it has to offer. It should be on par with the Air Arms S510 and similar European PCPs.
Cometas are coming!
This Lynx is just the first of a flood of Cometa airguns that are coming from AirForce International. Next week, I’ll begin a report on another exciting new gun. But focusing on the Lynx for now, I plan to chew on this report a little longer than the usual three reports — both because the brand is new to many of you and also because the Lynx has so many performance features that deserve to be fully tested. So, sit back and enjoy the ride!
More and more, we're hearing that airguns are ideal for firearm training when it comes to improving trigger control, acquiring a target and increasing accuracy. While all those are big pluses, let's remember the other reasons: (1) Save a fortune on ammo (if you can even get firearm ammo!). (2) Shoot at home. (3) No hearing protection needed. (4) Airguns are a fraction of the cost of firearms. So, click on the image & add this to your gun vault.
Sheridan has always made .20-cal. airguns. So, this new .22-cal. rifle is particularly exciting. And, it's available only in limited quantities. If you collect Sheridans (or just love them for their quality), you MUST add this to your gun vault. It's a single-shot CO2 rifle with a metal breech. Bolt-action single shots like the 2260 are ideal for teaching proper gun handling. Everything you love about Sheridan guns…and more. Get yours NOW before they sell out!
