I shoot 223's alot right now and am looking to step it up in caliber. After looking and shooting all the options I think 243 win is the caliber I am going to go with. The only concern I have is how many comments here and elsewhere I have heard about barrel life being short. Most people seem to be saying 1300 to 1800 rounds before the barrel is "shot out". When these guys are saying shot out are they saying won't hit a paper plate at 100 yards or just won't shoot quarter moa? I know all rifles are different just wondering what experiences you all have had. I completely get the rebarrel aspect but I am just wondering what to expect. I am planning on shooting out to 600 yards and will probably use a gameking in either 85 or 100gr. incase I want to use it on game. Thank you in advance for the help!
