I have a Win classic 338 that I bought in the 90’s. Winchester replaced it due to feeding issues that they could not repair. The replacement came with almost a 1/4” of freebore. Since I could not seat the bullets close to lands I modified the magazine replace the follower and changed the bolt stop. After all that I put it in Brown Precision stock and bedded with pilliars. Rifle shoots about 1.0-1.25 moa to 500 yards. I have been using 210 TTSX over reloader 19. This is one of my favorite rifles. I am considering adding a muzzle brake due to some neck and shoulder issues.
So after all that my question is about increasing powder charges. Since I am creating more powder space by seating bullet further out, should I be able to increase powder charges? Not sure I will, but seems like a lot of extra room in that case
