I was trimming some cases in the car on the way to work today
Good tip there, Gary.
And couldn't help but notice that there is a big difference in...
1. how much you have to trim off between the cases
2. how thick the actual metal is at the neck
All brass was once shot federal premium and all should have been from the same batch.
Is this normal, or am I doing something wrong at this embryonic stage of my reloading education?
