As in after how many shots? Carbon build-up is about the same as most rifles I guess. But 30-30 is a fairly slow bullet, so copper fouling should be less? I know my 30-06 seems to get copper built-up quicker for certain.

Is it necessary to clean it ever 20 to 30 shots?

I was just thinking about it and never really had a guideline to follow. Just usually whenever the mood strikes me.

Your thoughts?
