You'll be happy with the T3, you made the right choice, but you're not going to shoot through the same hole at 300 yards, just not gonna happen, I don't care if you're a long range shooter.
I shoot a 300wsm in browning a-bolt as well and the recoil isn't too bad. My gun came with the BOSS system and a muzzle brake, after having to take 2 shots at a deer once and my ear drums felt like they were going to bleed I took the muzzle brake off, and the recoil really isn't too bad, I felt I was flinching more because of the noise than I was because of the recoil.
