Thank you for taking the time to retype all that info -- I appreciate it.
Regarding your theory about the end being too small. I don't think so because, 1) the black powder loads didn't crack the hull & 2) the overshot wad in both cases fit perfectly. But wow that I think about it, I used a different lot of brass hulls for the smokeless loads. Maybe they are harder than the first ones -- I could try annealing them. It would be worth testing because the load otherwise worked great. I'll keep you posted.
