This is my first post so be gentle. Didn't know where to post this question. I figure all of yall must know what your doing to some extent. I'm just getting into reloading. I picked up two boxes of primers the other day , large pistol. After putting them all in I discovered one box was large rifle. My bad I should have checked each box but I didn't. So can I pop all these primers back out and tell the difference in the two? Or can I still use them like they are? What's the difference? 45 Cal. Thank you
