Thanks Tom, It seems as if each drum has a specific diet that it will work well with?... Most of my testing has been at the bench with some, now well worn, Winchester dummies that Ruff graciously loaded for me!
I have tried the truncated cone loads, and at the time, they didn't seem to help? But, recently, as the drum polishing sequence gets continually revised, I think they will work with most all bullet lengths and types... BTW, as of the 17 of this month, I have sent a total of 18 drum sets to Numrich, with additional quantities of nine every ten days.. until the current run of 75 revised drums are sent... More as we go along! Best to all, til....lat'r....GT....
