Puzzled. Need Explanation.
So I went to the range and shot some reloads. I wanted to check expansion of round but instead of expanding most of the bullets actually shrunk? I did crimp them But barely. What the heck is going on, I've never experienced this. The groups were ok.
I did some testing and non crimp bullets from magazine to chamber can add .010 to OAL. With the instructions from the crimp die it added .002 to OAL. I believe that's maximum crimp. How much is actually needed? Is maximum safe?
The best groups were at 28.5 grains of H322 with 110 Pro Hunter
6.8 AR platform
