Thanks for that tip Larry, that will e part of the procedure going forward. Sure enough, one of the remaining nine had a light charge, 1.2 grains. That would put 31 grains of powder into the round I fired. According to the Lyman Cast Bullet Manual the max load with a 185 gr. bullet is 29.0 grains. I wouldn't think a 2.0 gr. overcharge would result in this, but every gun is a story unto it's own. Ugh! Be careful gents, I'm certainly grateful that this is no worse than it is! My wife reminded me that if the gun is permanently out of commission it only cost me $20.00 as I won it at a gun drawing at a local club...........Women truly do think differently, that Venus and Mars thing.........
