Other than the pic loading upside down, what is going on with these loads?
I was loading up some 357 Magnum loads tonight, and this is the second time I have run into this problem. These 4 loads were the only ones this happened with out of 50. I run into this problem on the crimping stage. This happened with the previous batch I loaded as well with about 3 loads out of 50. I am using Hornady dies, and these seem to be the only dies I have this problem with.
Is something catching on the expanded case mouth and crushing the case?
