I've loaded and shot well over 10k of Wolf SM and LRG Pistol primers in .38S&W, .38 Special, .380ACP, 9mm, .40S&W and .45ACP.
1 Incorrectly formed anvil. Tossed it and moved on with life.
0 Duds
0 Hangfires
Very minor changes in load performance when I switched from CCI primers with Alliant Unique & Power Pistol, HP38/WIN231, Ramshot True Blue & Competition
Max ("Hot") and very light loads
Rounds fired in:
Enfield Revolver, Hi-Power, S&W 3913TSW, Remington 51 (Standard Triggers)
Multiple S&W Revolvers .38Spl and .45ACP, Multiple CZ's, Multiple 1911's (Match and STD triggers)
Never used them in a rifle load, but don't see why they would not be just fine in rifles too.
