Hardest ammo/primers to ignite

[kreuzlover]

Back in the mid-70's, I loaded all the ammunition for my business
partner who dealt in the sale of the original Automag pistols* I used only CCI large pistol primers as they had the rep of being the
toughest primers* The reason was that if I used any other make of primer, they would pierce, and it didn't take a genius to figure out how long those hard to get firing pins would last if those rounds were shot alot* To this day, if I'm loading hot rounds for
just about anything, I use CCI primers for that reason*

Spring kits make the action lighter. A good gunsmith makes it smoother and it feels lighter at the same time. A big difference in smooth and light.
