I was sick and had some extra time to think.
Now everybody understands the pressure rise with oversize HARD boolits ... but how much do they slam the cylinder forward when swaged through the tight throats? Or do they? Brass sticks to the walls...
I try to "slip fit" , reamers are in my "tools to get" -list.
But the question about oversize cast bullets unnecessarily straining the frame,the whole gun,is kinda puzzling me. J-bullets don't do that.
Thoughts,facts? Too much extra time?
