Re: When to Clean
I think it depends on the particular rifle. I'll always try to find out how many shots I get before accuracy falls off. For my hunting rifles, I use just about the same solvents, cleaning procedure, and shot count that you use. Unless the rifle is subjected to rain or moisture ect., this gets me through a particular hunt, or sometimes the season. I confirm that my hunting rifle can go at least 50 rounds without cleaning and hold it's accuracy. I suspect that could go higher, particularly with my R5 barrels. This is more a function of factors other than worrying about overcleaning, which I have not found to be a problem if done properly. My competition rifles are tested for much higher shot counts and I generally go 150-200 rounds between cleanings. This is done more for convenience, cost, and time saving. I have found that it generally takes 4-10 shots to stabilize my velocity and accuracy with a clean barrel. IMHO.
