Dealing with subsonic loads, has anybody done any testing on primers with 300 BLK loads? I've been using Rem 7 1/2's because that's what comes in the brass. Going to start reloading fire-formed brass. Just wondering if anybody has taken their developed load and tried it with other primers to see if it changed anything.
300 Blackout Primers

I run CCI41's almost exclusively simply because they are easy for me to get and some times cheaper than regular primers.
Supposedly the Win primers are quieter with the subs, I dont know.
I want to try some Wolf/Tula's because they are supposed to be very good for very cheap.

My first loads for my .300 black out were with small pistol primers. Several had holes blown through the primers at the firing pin indentation. No issues with federal small rifle primers.
I've not yet used Tula small rifle primers in my .300 black out but they have been working great in my .223 reloads and should work just as well with the .300 black out.
I'd steer you away from Tula small pistol primers (for pistols) as I've had issues in my M&P pistols with those primers.

I use nothing but Federal small rifle primers in all my 300 ammo. Both subs and supersonic.
ES and SD numbers are low and accuracy is good.

I have used all kinds and brands but the Remington primers, I have had pierced primers with subsonic and small pistol, I stick to small rifles from now on and standard or magnum makes no dif in my experience.
