Did I finally do it?!?!

Did I finally achieve the proverbial "holy grail" of PCP air rifle enthusiasts world wide? The benchmark that all slug shooters strive to attain? The infamous "sub MOA" tune/group on the gun?

Let me start by saying this. I purchased my first PCP air rifle in 2017. It was a used, stock AirForce Condor SS in .25 caliber. For most of you that don't know, the AF Condor is a non-regulated PCP with a "inline" bottle/valve configuration. The guns weren't designed for shooting at benchrest competitions. They were designed for hunting utilizing EXTREME power. They're still unmatched in power today, in any particular caliber. 

The reason I bought this gun was because (frankly) I didn't know any better. Thinking back about 15 years ago, I remember my Uncle Curtis (RIP) telling me about this air rifle he bought, and how much fun it was to shoot. To say this man loved guns would be an understatement. At the time of his passing, his gun collection had surpassed 200 pieces. As a kid growing up, I always had a BB gun. The first I ever owned was the Daisy 880 pump action BB/pellet air rifle. I was 11. Still to this day, I love that gun. Many a furry woodland creature fell prey to that gun. 

Well, when I was a sophomore in HS, I got a Benjamin in .22 caliber. I don't remember the model, but it was a 5 pump, and I could take head shots on ducks at 35-40 yards when I hid in the cattail reeds that surrounded the pond. That was all naked sights. No scope. But that gave me a taste for more power from an air rifle. That was a long time ago (1991).

So in 2017 I got this hankering to rekindle my love for air rifles. Given I'm a "big boy" now, and I have a decent job and can afford a nice air rifle, my mind tracked back to what my Uncle told me over a decade earlier, so I opted for the AF Condor. I didn't research PCP's. It was a name I knew, so I hopped onto eBay and found one used with scope, bi-pod, and a few other accessories for around $600. Had I know what I know now about PCP's, and where the technology would be going, would I have bought the AF Condor. Uh.... NO! I would have saved up for a FX Impact. But it's hindsight now, and this is how it happened to play out for me. 

I started shooting the gun un-regulated. Believe it or not, that thing was a tack driver. Not in the same class as a FX or Daystate of course. But compared to what I remember air rifles doing, It was a HUGE step up in power and accuracy. I was taking head shots on dove that perch on a light pole at 40 yards. This curbed my craving for a while. Until....

Then I got sucked into the YouTube videos by Ted, and Matt, and Gerard, and Stephen (from AVS), and others who I've come to respect HIGHLY because of their time and energy regarding the research and effort they've put in to help make us better shooters, and more humane hunters. 

About 2 years ago, the slug craze hit HARD. I remember seeing videos by Matt and Gerard where they talked about the pellets being more accurate at all ranges, but slugs having way better BC and retained energy. So when you could connect with a target, the carnage was FAR beyond what a pellet could do. 

Then those guys started tuning their guns. They realized this was shooting, not horseshoes. Close wasn't good enough. I think the greatest pioneer to the air gun world (hands down, no one comes CLOSE) is Matt Dubber. Matt, if you're reading this, you are the GOD of air rifles, and your research and time have transformed this sport! Thank you! I'll never forget the video that Matt posted where he was invited to the FX factory and they starting pumping out barrels with different twist rates to test ON THE SPOT. It's a cool video if you've never seen it. 

But back to my situation..... I caught the bug, and shooting slugs became my quest. I've done a TON of mods to my gun. The only thing stock left on it is the frame. Everything else is an upgrade. But even with all the upgrades, the "holy grail" has just been a myth for me. The downside of the Condor is it's mechanically "clunky" and simple in it's design. This makes it very difficult to tune. But it is tuneable. It's a laborious and time consuming venture that takes a massive amount of patience. Like I said, the downside of the AF platform is it's designed for power and hunting, not bench rest shooting. BUT..... BUT..... If you can find the magic combination- the proverbial "resonant frequency" where all the stars align, you can get a very, very accurate rifle that also has a ton of power. Well guys..... Today..... After several years of striving (along with plenty of money spent on regulators, custom barrels, slugs, scopes, bipods, and copious quantities of my sanity) I did it! I found the magic combo today. And MAN.... Is it accurate! 

The following pictures are representative of a 10 shot group at 40 yards (which is as far as I can go at my house). But it's 40 yards on the dot. I remember seeing Matt shooting his Impact and getting a ragged hole at 40 or 50 yards, and thinking to myself, "If ONLY I could get my gun dialed in to replicate that." 

So here's the set up:

AF Condor frame, 24" .252/.246 barrel with a 1:15 twist, PCP Tunes V3 regulator, AVS 40gr HP cup base slugs in .254. Slugs are going 945 fps (just under 80fpe). I tuned the gun to a shorter length of stroke when the hammer hits the valve, so I'm not wasting any air. Here are the results of the 10 shot group.

The group size center to center is .2835" at 40 yards. That's sub MOA. If the accuracy carried through to 100 yards downrange, that would be .71". But I've NEVER gotten accuracy like that with my rifle, even with pellets. I was shooting from a laying position with my bipod and a bench leg that is part of my gun stock. I'm kind of shaky by nature. If this thing was locked in on a bench vise, I think the group size would be even smaller. 

But given that it's taken a huge portion of my sanity, time, and money, I'm never going to change the settings on the gun again. I bought 400 of the AVS .254 40gr HP cup base slugs today, and those are going to be my permanent slug for this gun. If you're getting pellet accuracy from the gun, why switch? You don't leave fish to go catch fish (a wise fisherman once said). 

Here's the gun:

Thanks for letting me share. 


 
Hey Scott, thanks for sharing your experience of getting into Airguns. I too started back in 80s with a daisy 880 single shot 10 pump. I was hooked from that moment. I picked up the bug the same way you did. I watched Ted, Matt and countless other you tubers teach on the subject of PCP Airguns. It's amazing how PCP have changed so much from 2015. When Gerard show cased the ATI Nova Liberty in one of his early videos I was hooked. I thought can a $300 Airgun shoot sub MOA 10 shot groups like the more expensive guns. 

Thank you for the mention and I'm so glad things are working out with the air Force condor. I love that gun. Might have to buy one. 

Where did you get thank stock? I like it.
 
Great post ... what is your fill pressure..how many shoots you get on the reg ... I buy one but haven't been able to test it yet..thanks

My fill pressure is 4300-4500 psi (as accurate as the inaccurate gauge on the regulator reflects). The reg pressure is set at 225 BAR. I know that seems like a lot of pressure when compared to the FX Impact, but it's all about plenum size. The plenum on the FX impact is HUGE. The plenum on the V3 reg from PCP Tunes is significantly smaller. However, PCP tunes makes the Texan regulator with a large plenum. So I could probably achieve the same velocity with the Texan regulator set at 180 or 190 BAR as I could with the V3 reg set at 225 BAR. To be honest, I would have bought the Texan regulator right off the bat, but at the time I decided to regulate the rifle, PCP Tunes didn't have a Texan regulator. They only had the V1 and V2 reg. That's what I started with. Not only could I NOT hit sufficient velocities with slugs using the V1 and the V2, but the reg could only take up to 250 BAR bottle pressure. The V3 reg can handle 310 BAR (4500 PSI) bottle pressure, and the regulated side is adjustable from 150 BAR to 250 BAR, and it has a larger plenum than the V1 or the V2. So with a 4300 PSi fill, and the reg set at 225 BAR, I get 18 or 19 regulated shots at a velocity of 945 FPS, with an average extreme spread of 4 FPS before the reg drops off.

I would have gone with the Texan reg if it was available when I started upgrading my rifle. But all they had at the time was the V1 and V2 reg. AF rifles are very hold sensitive due to the inline bottle configuration. The point where the bottle attaches to the frame induces flex, that can equate to inaccuracy downrange. So you get around this, I ordered a custom stock from Mad Dog rifle stocks. That way I'm shouldering the stock of the instead of the bottle, and this totally eliminates flex. Doug Russel is AMAZING! I sent him the measurements, and he built me a custom stock. But the stock was built around the V1 regulator. And it has a very tight tolerance. Fortunately, the V3 reg fits the stock, even though it has a larger plenum. But it fits with zero room to spare. The plenum on the Texan regulator is 3 times the size of the plenum on the V3 regulator, so there's no way it could fit on my stock. I would have to order a new stock, and send Doug my rifle to have it fit up. That's not going to happen. Maybe one day, but not any time in the near future.

But I've been able to make 80 FPE with the V3 reg. If you have this regulator for your Condor, you won't be able to make the same power as the rifle makes un-regulated, but you can still make critter killing power! 80 FPE is nothing to scoff at. That's what the FX Impact in .25 is making. I've also placed .06" of shims (6 x .01") under the shoulder of the tophat to limit the length of stroke. AF rifles are notorious for wasting air. They are mechanically clunky, so the adjustments aren't typically done in precise, controlled increments. So by shimming under the shoulder of the tophat, I limit how deep the valve can stroke when the hammer and breech strike it. I figure out what my max velocity is for that regulator setting, and start bumping up the power wheel until I get to a level that I don't see the velocity increase any more- I just see the tank drain faster. Then I remove the tophat, and start shimming it up underneath. I found that when I got to .06" of shim, my velocity dropped by 5fps at the same power setting where I was getting max velocity. By doing this, I'm confident I'm not wasting any air. I'm getting just enough to achieve desired velocities, with zero to spare. This is the beauty of the FX or Daystate rifles. You can externally tune the rifle to accomplish efficiency MUCH easier than you can on the AF platform. 

I'm also running a custom barrel. Not the stock LW barrel. The custom barrel is a .246/.252 (land/groove) polygon, carbon fiber wrapped barrel with a 1:15 twist. My buddy Alex in Russia made it. It's a beautiful piece of machinery. And I'm shooting the AVS .254 HP cup base slugs. They concentrically seal the grooves as well as fully engaging the lands inside of the barrel. This also eliminates wasted air. If you've never used slugs from AVS, they are superb! He's the ONLY manufacturer out there that makes slugs in unique sizes within a particular caliber to reduce or eliminate wasted air. His slugs are swagged in .217, .2183, .223, .2503, .254, .2573, .3003, and .3083. That .0003 does indeed make a difference. He has flat base, cup base, dish base, and hollow base options. His slugs are VERY consistent, and I absolutely love them. He sells sampler packs. I would encourage anyone on here to buy a sample pack of the slightly larger slugs and see if your gun likes them. My gun liked ZERO of the slugs from NSA, VK, or Griffin. It ONLY likes the slugs from AVS. Not to knock the other guys slugs. They make a good product. But none of them offer slugs in the same sizes as Stephen at AVS does. 

I'm an open book. If you're interested in replicating my results, I'll tell you everything I did to make it happen. It will probably cost you some money, but not as much as a FX or Daystate would cost. There's an old saying- a wise man learns from his mistakes, but a wiser man from the mistakes of others. I mad a lot of mistakes trying to tune my gun. If you goal s to make an accurate AF rifle, learn from my mistakes and take my advice. You'll save yourself a lot of money and frustration.

Where did you get thank stock? I like it.

I bought the stock from Mad Dog Custom Rifle Stocks. Doug Russel is the owner and founder. His work is superb! If you need anything custom, he will do it for you. The regulator I'm running on my Condor adds 2" to the length of pull. So he had to get creative about making a stock that accommodated that- and he did. 

The downside of the Condor is it's a single shot rifle. 1 slug at a time. But it is what it is, and it's all I have. And I'm ok with that. 

Stephen with Air Velocity Sport also showcased the ATI Nova Liberty. He did some regulator mods and I think he even made a custom wooden stock for it. he explains exactly what he did to accomplish this. He's definitely an innovator, and possibly one of the more under-recognized guys in the YouTube air rifle video world. 


 
My first airforce was a .22 it was a acurate but inconsistent gun..then I go for regulated gun I have crickets now..an used to have taipans to...but I never sell the airforce it is a gun a could work on .. from my regulated guns I I lern that the only thing missing in the airforce line was a regulator...the altaros is for light pellets...sold that n purchase the pcp tunes condor v3 reg ..in a few minutes I could manage to achieve the speed I was looking 940fps with 25g slugs in a 18" airforce barrel with a modified 2 top hat of the rimlock valve kit n still have 2 more top hats sizes to go..and a 24" barrel. 22 that is great I could shoot in their respective power from 11g pellets to 40g boat tail slugs with pin point accuracy...n now regulated it with be even better..the regulated buid is my latest one..the others are one .223 condor...257 condor. 257 texan 308 texan..externaly reg ..... the 257 condor will later be 7mm...I could buy n sell my other rifles but my 5 airforce go with me to the grave...funny thing is that when the texan v3 exploded..every body trash pcp tunes..but no body come with a solution to regulate them .. even when there are regulated airforce since 2012...for now I will use the regulated buid in .177 .20 .22 ...for the .25 I have a unchoke tj 18 1/2 long I shot awesome externally regulated..with a reg man...when I find the correct bottle for the job will buy another reg for the .25 ...thanks for your time...I do the builds but not a lot of time for testing 😁...is good to know that I could consult with you . Before I damage something.

Well that guy you just replied to is who I think you are describing...
