Well, I finally decided to run a shooting test, using the same .222 load with three different primers: Remington 7-1/2, CCI 450 (latest version with the hotter priming compound), and Winchester Small Rifle. The WSR is supposed to be somewhere between a standard and magnum SR primer in brisance. Also decided to use Ramshot TAC, as hotter primers tend to make more difference in velocity etc. with spherical powders. Will report on the results.
