We take 2 identical 30 PPC cases.
The first one we shot at the same target 20 times, reloading without annealing in between each shot.
We did the same thing with the second case however this time we annealed the case on our MARK II annealer every reload. This is the difference.

Special thanks to Lou Murdica who helped us make this experiment possible!
