Hopefully someone can help! I have a Winchester Model 70XTR in .22/250. I assumed it had a 24" barrel, but it actually has a 22" barrel. Will this affect velocities, accuracy etc. It is mainly used for shooting foxes, kangaroos and goats. I am thinking of re-barreling in the near future and am wondering what length barrel I should go for. Also what twist would be recommended as it currently has a 1-14 twist. Should I go for a 1-9 or 1-10 twist? :?:
