Greetings,

I have a good..let's say A LOT of magnum rifle primers Wolf. Can I use them in my M1A and not be afraid of slam fire?

Thank you

I've used maybe 10K SR Wolfs (non-magnum) in ARs without incident. Doesn't mean I won't experience a slamfire tomorrow, but I'm not terribly concerned about it.

I have read a number of posts where people are complaining that Wolf primers are hard to seat, and hard to ignite.

That is just wonderful as that means they are likely to be military primers.

I have 5000 but I have not reloaded any cartridges with the things.

Avoiding slamfires is a process, not just a primer issue.

You should always full length size your brass. Short of industrial sizing equipment, small base dies will bring your brass as close to factory dimensions as we can get. But you have to use a good lube such as RCBS water soluble or Imperial sizing wax. You will stick a case with spray on lubes.

You should set up your sizing die with a cartridge headspace gage and size to gage minimum. Without one of these gages you have no idea just how much, or how little you are sizing your case.

With mechanisms that have free floating firing pins, you absolutely do not want any delay to bolt closure. Sizing the brass down to original factory dimensions and ensuring that cases are not over long reduces the chance of an out of battery slamfire.

Bolt gunners can get away with neck sizing and crude sizing practices where all they have to do is crunch the ammo to the chamber by beating on the bolt handle. Gas gun shooters must be more particular to make safe and reliable ammunition.

I have been using this K&M primer pocket reaming tool on all my M1a brass. Since all my 308 brass could be fired in a M1a I am reaming pockets to depth on most every 308 case I have.

The reason for reaming is that primer pockets collapse over time, and are seldom uniform in depth as they come from the factory. Just ream the pockets to depth and seat all primers by hand. Verify that nothing is above the case head.

Hehehe

That is a lot of information. I do all that.
I was just curious to know if wolf primers were not the soft type so they can whistand the inertia of the firing pin. I use the wolf 223 and magnum in my ar with good results. But i did not know if the magnum large would do the job too.

Thank you
