    I love my SS. Very accurate I have taken a few big hogs at over a hundred yards.

    Very Nice.

    I was thinking of putting a 24” barrel on my .357 but it shoots so nice I don’t want to change it now. Condor SS in .257 would be nice, I’d buy one if the FPS  was still up there.

    Complaints about poor accuracy for .308 Texans abound, yet other Texans in different calibers can be very accurate out of the box.

    I know several shooters that have three or four Texans and all have told me of problematic .308's.

    Nick at NSA himself has commented on having problems with developing a good bullet with his .308 and that it took much more work than any of his others.

    Note my .457 Texan can and has frequently shot 1.25" 3 shot groups both tethered and off tether at 100 yards, and I'm a 63 year old 'shakey' guy, haha..  And the .357 is similarly accurate.  Multiple .257 shooters have gotten 1/2" at 100 so it's not the gun itself.

    No one I've communicated with has told me a 'solution' and Air Force denys there is a problem.  Interestingly enough, I know two people who had their .308's re-barreled AS .308's and the change made them laser accurate compared to the factory barrel.  So it's not the gun itself but 'something' in the barrels they used.

    Personally, I'm going to go to a 7mm barrel and dropping 308 for the better SD and BC

    I nearly bought a .308 but I also read about problems with accuracy and went with a regulated Ataman .357 instead.  The crown might be the issue but I really don't know why those Texan .308 are having issues.

    You are correct, the complaints on the 308 have been out for awhile now and I’m surprised AF hasn’t done anything to correct it.

    AirForce has been spending a LOT of time and resources filling RAW back orders according to my sources.

    They were working on a multi-shot gun till they bought RAW and shelved the multi-shot (temporarily I hope).

    My .308 Texan SS is actually a tac driver with pellets. 

    Have you checked the tightness of your barrel set screws and your scope rings?

    @bullfrog out to weigh in on this again. His .308 was spot on (with pellets!) then it turned on him. Even made his hair turn grey for a couple days 😉. Seems to be resolved though(?)

    Yes I can add something, not specifically for the .308 but something that probably applies to all Airforce guns. 

    I had the priviledge of hosting Brian this past weekend for some whitetail and turkey hunting on my farm in north Florida. Between hunts we did a lot of shooting. My .308 started acting up and spraying everything we put in it. I polished the barrel and tried every other small fix I could think of and we were still getting odd fliers between groups of 2 or 4 semi tight patterns. 

    Brian suggested we tether the gun. When we did so at or around 3200psi, it became a laser with everything we put in it at 50 yards. When we untethered it, it started spraying again, even though velocities didn’t significantly change. We speculated that perhaps the changing of the pressure during the shot string was causing violent vibration in the gun.  I then checked the spin loc tank and saw that it was hand loose. All weekend it had been coming loose and I had been hand tightening it whenever it came loose. 

    We took the Airforce wrench that’s made for the spin loc tank and tightened down as tight as possible. Then the gun became a tack driver again and has been so ever since. 

    I’ve thought back to when my Condor was fickle, and often I’d keep the spin loc tank hand tight and not tool tight. Its a very accurate gun now, and conicidently (or not) the tank is also very tight. 

    I tool tightened my .45 SS and its also now consistently drilling with Nielsen 290s at 50 yards.

    Finally, my brother sent me his Condor to diagnose his own accuracy issues with it. The tank was loose to the touch. I’ve got it tightened down good now. I’m going to polish the barrel then shoot groups with it. I bet the tight tank will solve the problem.  

    Again, this is a fix more for all Airforce guns and not the .308 specifically. I think a loose tank is contributing to frame flex and may be the reason Airforce guns can seem like they shoot awesome one day and poorly the next  

    As far as .308s, my .308 likes the following:

    45 gn JSB pellets, 45 gn Polymags, 50 gn JSBs, 59 grain NOE cast pellets, and 99 gn Nielsons. Out to 50 yards anyhow. I’m not interested in deer hunting beyond that range. 

    If your gun’s barrel just doesn’t like the above, I don’t have an answer for you. But do suspect frame flexing relative to tank tightness  if your gun seems to be fickle with anything you put in it.

    ON an Airforce gun a loose tank means inconsistent contact between Valve and hammer / breech / bolt which leads to inconsistent velocities as well. 

    If the valve is canted one way or another nothing will be consistent. That is why the spin lock system has a wrench AND a locking set screw for the collar.

    In case you can't tell I have made this mistake also in the past. I now have 8 Airforce guns and all shoot consistently and accurately.

    I check my tanks all the time and now they both are staying tight, my .357 would loosen up and I’d back off set screw tighten tank and re set the screw, it did this a few times and now it’s been staying tight, my 45 hasn’t had a issue yet.

    Loose tank is not my issue, I know because I broke the wrench trying to remove the tank to have filled. AF did send me a new wrench . I am wondering about the bullet grain. The lightest I have put through the barrel is a 108gr . Yall seem to be shooting much lighter rounds.

    I broke my wrench too, without applying much force. Any tips on getting the spin loc collar free without having this happen? Does having pressure in the tank make it harder to loosen the collar?

    Are you sure you loosened the grub screw first? If the grub screw is out, try turning it with your hands first.

    Edit: “It” meaning the bottle.

    I shot this video just to demonstrate the accuracy with light ammo I've been talking about. That, and because I couldn't find anything about the .308 SS on youtube when I looked for reviews before ordering it.
