In the single shot rifle category I was reading about chamber ringing, most state that small powder charges in larger cases causes chamber ringing and excessive pressures. All my rifles 7mm, 7x30 waters, 30-30, 7.92x33, 32H&R, 7.62X39, 45-70 I want to use mouse fart loads. Am I asking for trouble? I have used a Dacron wad to hold powder in place in the past but, now I'm getting nervous. What is your thoughts on this?
