Interesting report. Just curious - why were you using those CCI #34 primers? Those things are HARD, plus are usually tough to find in my area.

Bought 15,000 a couple of years ago at a great price. The only problem I've seen is on a Ruger .257, 38 years old with a slightly weak fireing pin spring ( miss fire with first strike).

You also must adjust your thinking when looking for pressure indications. The hardness seems to mask high pressure signs somewhat. roger
