Took the Gibbs to the range yesterday to see if it was the weather, my nerves, ETC, ETC and last night as I was drifting off into sleep it dawned on me that that had happened before! Sooooo this morning I did a search and sure enough it had and the cure was re-casting the bullets as they had hardened up a bunch from sitting so a new cast with soft pure lead cured the issue. I pulled out my Lee hardness tester which seems to be pretty accurate and the next bullet in line I was going to shoot had a hardness of 14.5 which is pretty hard. My pure lead bullets freshly cast usually run about harness of 8.0 to 8.2. So it appears I will do a bit of casting tomorrow since the weather is supposed to be nice and only cast 50 or so bullets and NOT let them sit for so long. There are several posts that talks about this which were started by me if you want to look.
