Can anyone help me with figuring out the safety of using large pistol primers in place of large rifle primers for .308 . I have cci 350 mag. l.p. primers and Rem. 2 1/2 l.p. primers. I am having a hard time finding large rifle primers in my area. I know that the only size difference is the thickness. I can't remember which is thicker and don't have any large rifles to check . I believe the rifles are thicker. I also believe the mag. large pistol burn rate is real close to the large rifle. Can I interchange these if my firing pin is long enough to strike the primer? Which primer should I use? Thanks in advance for the help. ISME
