    Question about Mag pistol primers and Mag Rifle primers

    I just started back reloading again after a 15 year hiatus. My reloading components are still in great condition. My question is ....What if any is the difference between Large Pistol magnum primer and a Large Rifle magnum primer? Seems they are the same size, am I able to use them interchangably or not? Mahalo (thanks) in advance.

    I believe the rifle primers are harder to ignite than pistol primers

    I dont really think I would do it. There has to be a reason---maybe the rifle primers have a bit more priming mix in them making them "hotter", which would cause a pressure increase.

    I think your right, there must be a reason for making the different types of primers. I guess I had better be more careful in the future, as i did load some 45 ACP with the large rifle primer......it was a reduced load......but did seem hotter then usual

    yeah, I think I read in one of my manuals about the rifle primer being thicker

    Rifle primers are a little thicker/taller than pistol primers. Do not use them in pistol rounds.
