Re: Shot count between cleaning
For the Blaser 308 and the Remington 260, accuracy falls off after 150-200 shots, just a little bit, and then tightens right back up after a good cleaning. The 223 seems to go 500-750 rounds, and then I clean because I need a break, not the barrel.
For the .264 WinMag and the .300 WinMag, I never let it get that far, as I like the predictability of a frequently cleaned barrel. They get cleaned after each range session, and then at the end of hunting season.
Personally I have never seen a barrel damaged from cleaning too much, just from cleaning incorrectly - but I don't have nearly the experience as others on the board, so I'll assume they're right and that it's possible.
