I decided to do a cut away on Hornady .308 brass. Three times fired. The reason being I wanted to see what it looked like for a paper clip test. After only being fired three times there is no damage at all. I thought there would be something.
This piece of brass was loaded with 4895. 41.6, 41.8, and 42.0gr
