Have your gunsmith check the rifling just ahead of the chamber. Depending upon how many rounds you've put through it over the years, you might see the first few inches of rifling worn almost smooth.

Our M24 (Remington Custom Shop) sniper rifles in 7.62/.308 were rebarreled after 10,000 rounds. Hotter rounds call for rebarreling after much fewer shots down the barrel. If memory serves, I think the .300 Win Mags got new barrels after about 2 or 3 thousand rounds.
