So, I was at the store yesterday and thought I was in luck. I see large magnum primers. Then as I calm down and read the box it says large magnum pistol primers. I didn't buy them but now I'm wondering if I made a mistake and could use them in a rifle. Has anyone tried this? I'm running low on magnum primers. I have a ton of large rifle primers because that's what I use to load a lot of. Now I'm loading 2x more magnum. Would it be better to use a regular large rifle primer or the large magnum pistol if I run out magnum rifle?
