Thx. I bought some 270TSX for my dads 375 Ruger with the 20” barrel. It’s shooting .5” three shot groups at 100 yards with a book max of RL15. I’m guessing 2600 FPS or so but I haven’t chronographed it. I chose it over the 300 because X’s “thrive” on velocity and out of that short barrel I wanted to try to get as much as I could. We should be hunting herds so I was also scared of having the 300 grainer shooting clear through. I did finally get in tough with Bill from Swift bullets but by then I had a 1/2” load using the 270TS. My RUM is shooting them at about .7” and groups are getting tighter as the powder charges go up, but so is the recoil. I think my last load was 96gr of H4350 and I think the max is 98...but it was a lot nicer to shoot at 92.... if a 270TSX @2750 won’t kill u buff I doubt an extra 100fps will matter. FWIW the TSX are quite a bit more accurate than the 300 A frame factory loads out of my rifle.
