TWO QUESTIONS #1 I'm shooting 308 with at least 1000rds through the tube. Should I change the barrel before I try to start working on loads with the long range stuff so that I'm starting everything from scratch? Yes Yes I know 308 isn't the best long range caliber. #2 with a standard Remington 700 short action chambered in 308 can I rebarrel in say 7mm WSM??? or do I have to get a stronger action? Thanks in advance.
