Federals are the choice of most revolver shooters. They apparently will ignite with a slightly lighter hammer strike, which happens when you lighten up the trigger pull. That being said, some people don't like them in there auto's in fear of a slam fire type of event. That is only some people. I used them for years in everything with no problems. I now use Winchester primers just because I can get them easier and I like there packaging better. Accuracy??? meh, my skills don't show any difference. YVMV RR
