So I bought myself an AirForce Texan SS .45 for Christmas..

Oh boy! The fun begins. Can't wait to hear your impressions of both, the gun and the 4K Pro. 

I to would love to have one to go deer hunting with let us know how it shoots. Congratulations 

I've had a .45 Texan SS for a month or a bit more now. Here's a few things I've found:

1) Watch for clipping in your shroud. Both my .45 SS and my .308 SS have had issues with one baffle clipping. In the .308's case, the baffle was drilled a bit off center. I fixed it by simply opening up that off center hole. In the case of the .45 SS, the first baffle is smaller from the factory than the other baffles and shaped differently. I had to open it up significantly. Once I did so, I started getting tighter groups with a bunch of different kinds of ammo. Before opening up the first baffle, I only got good groups with heavy ammo. 

2) Mine can shoot 220 grain ammo in the 880s fps. My initial chrony results were lower than factory specs, but then I discovered my chrony was worn out from several falls over the years. Changing chronies put my numbers where Airforce says they should be. The tightest shooting ammo in mine is Nielsen 290s. With the bad chrony, they were flying 720. I suspect they're really doing about 800fps or so. But I have decent results with the lighter NSAs now that my clipping problem is solved. To my mind, if I can have my ammo of choice shoot 850 or better, that's plenty of power and velocity for at least to 50 yards, which is the max I'd take game with it simply for trajectory's sake. For myself, I'm not considering the upgrade kit simply because I presume that the extra power may make the gun too loud for my tastes. 

3) It shoots Hornady round ball .457 well and is therefore a good plinking round. NOE is about to release a .45 pellet mold that may be a good ammo choice for this gun for higher shot count and max velocity. 

Tag, as my 45 SS arrived yesterday

I have had my 308 SS for a couple weeks and just love it way more than I thought I would! Shoots nice, loads easy, groups nice also. I have shot it out to around 100 or so plus yards and have no problem nailing a 22lr spinner target. Thwack!!!!!!! It is amazing at how much harder it hits over the 25cal Vulcan I have! Can’t let the wife know but the 45cal is next.

I just watched a video from SouthernGunner, where he takes a larger bottle from a Hatsun and fits it to a new .25 Gauntlet. The bottle has an external regulator and he filled it to 3800 PSI. After shooting regulated guns I"ve became spoiled, shooting the Texan SS I would love to see a similar set up made for the Texan's. How difficult would it be for them to offer a similar product with an offset that would lower the bottle or a newly designed say oval bottle that would allow a scope mounted closer to the bore. I'm ordering some NSA slugs as home casts and shooting untethered is not yielding any accuracy or consistency.

Given how the Texan and other Airforce valve work, I’m not sure how you’d have enough plenum space to make the power you need to in a regulated Texan. I know my .308 SS does 100-110fpe with light pellets at 2000psi for several shots. If making it into a magnum pellet shooter was your goal, the pressure would be right for regulation. I just don’t know how much plenum you’d need. 

Speak with Doug, he has likely done very high powered .45 cals regulated. You can pm me for his email as I don't want to make it public here. He's the king of Air Force guns.

Tried it but unfortunately the bore through the offset choked the airflow and I lost 200FPS. Doug has looked at it and said he didn't know of a way to make an offset work with the current valve size/threads.

He has done work on regulating but told me the key to Texan power is the whole bottle is the plenum. Sure it could be regulated... With a plenum the size of the current bottle and a remote regulated bottle feeding the plenum which you would mount where? Basically impractical.

TheTalonTunes offset is designed and works for the .17, .22 n .25 guns.

Anyone want a one time used TalonTune offset?

I’ve been shooting the NSA 220 gr swag hp’s for a year now with my Texan 45 and it’s definitely a 80-100 yard shooter, three shots and I refill, I haven’t had a chance to shoot beyond 100 yards yet but Im not worried about anything under 100 yards, it just likes those NSA 220’s, I do have some NSA 270’s but have yet to try them being the 220’s are so nice.

Good info. Thanks everyone. I'm excited to start playing around with ammo for my new Texan.

I got a .45 SS too and have to shaved off a bit of the internal and now all good. Love this powerful tool. 

I have one of the first Texan SS 45 caliber. Try Nielsen 240 grain or their 372 grain. Back off 2 lines on the power adjuster and be prepared to be amazed. At 50 yds with the 240 grain on a full fill I get 6 shots you can cover with a nickel.

anyone know if texans can take 4500 psi ?

The manual says not to go over 3,000psi. 

It’s only a aluminum bottle, definitely would not try to take it to 4500 ,,I’ve filled mine to 3500 tones of times though with a mag spring,, but it has a 4500 bottle on it now it’s the 308 pushing 350 fpe ,, you can purchase a 4500 bottle from aliexspress for 31 bucks shipped...

I have had my Texan SS for a few years now, all was well till a few weeks ago... Started shooting all over the place... process of elimination ruled out the scope, I pulled the shroud after calling AF and found that my end baffle was being clipped... the first one closest to the muzzle has smaller bore hole than the other three. I have run through the entire rifle looking for anything that has come loose and all is still factory tight. I have cleaned the barrel inspecting for lead and it is clean. I have only shot NSA 220g swagged ... any other suggestions????
