As long as the primers are made for semi-rifle use you will be okay. I once made the mistake of using .223 magnum primers in some 9mm pistol stuff I reloaded. I could only get one of about 10 to go off in my glock. And that was trying to get them to go off. A floating firing pin hits a lot softer than a glock hammer.
