Looking for some advise or opinion on something I encountered last night. I'm relatively new to loading. have loaded a few 100 bullets so far, 9mm and 45 acp. Last night, I was getting some jacket shavings or splinters about 1 out of every 5 bullets both in the 9mm and 45... I do not remember running into this before. Using casings that have been shot 2 times now.. This will be the third load in them.. This normal? Suggestions? Thanks in advance. Chris.
