If you want to go over 300 grains in bullet weight, then I suggest that you increase the twist rate from 1:12 (standard) to 1:10 or even 1:8. Woodleigh offers a 350 grain .375 bullet, and Rhino Bullets of South Africa offers a 380 grain bullet. Overly long bullets will tend to destabilize when they strike an animal unless the twist is fast enough.

And you are correct that the Barnes TSX 300 grain bullet is very long and is likely to show instability when it hits a game animal if fired from a standard twist. That has historically been a problem with the Barnes X .416 400 grain bullet and the Barnes X .458 500 grain bullet.

Good luck!
