Sorry for this lame answer but with new 4500psi tank, 6-10 at most within a 40 fps spread? Original 3K steel tank, lol, 2-4?
I’m friends with the guy that tricks Texans out and competes. He runs a huge buddy bottle on his .257 for 7 consistent shots. We’re quite different from each other in he competes, I wouldn’t ever spend time/money traveling to compete. I still love .177 spring guns. He hates them. I’d prefer to shoot tethered where he/most would not.
Point is any of The Texans, new 4500psi CF bottle or not aren’t meant for a lot of shots. I personally want a 6K step down in-line reg & 8-10’ of hose to set up on a BR or bipod & shoot targets or varmints, consistently, shot after shot. I have a big compressor so it’s logical for me. If I’m gonna put a 3/4”-1” 36” 1:12 or 1:13 chrome lined Bartlein or PAC-NOR, maybe a Bobby Hart, it’s all for nothing if my slugs aren’t all within a 10-20 fps spread at most. The reg should have 10 fps or less but my sizing slugs 0.0003” over is a huge part of consistency/accuracy.
