Great primers
By Jeff D. on Feb 09, 2025
I’ve been using these in my AR10 308 and started using them in my AR15 762x39. They are a magnum primer and I have to start low and work up on 762x39 loads. CFE BLK load I did with these are supposed to start at XX. But XX.X started showing big pressure signs with primers starting to pop. So Most starts are max with these primers in 762x39. The XXgr is a good max load. Just use caution.
I USE ON THE PSL

I use these CCI #34 primers because they are harder than regular primers and will prevent an accidental SLAM FIRE on Rifles with free floating Firing pins. I had never had a SLAM FIRE and I don't want to risk having one. That said , keep in mind these helpful tips. These are Magnum Primers and even though they don't specify on the CCI Webb page but they are. Now , you have to start with Light Loads (according to your caliber and reloading manual) and work your way-up. other wise you'll have dangerously high pressures. These primers can be used on 30-06 , 7.62X54R and I've heard of them being used in the 7.62X39. I've just started using them and so far I'm pleased with the results.
