Shot my first 300BLK Rounds!

Post by TracyRifleandPistol »

I decided to jump into the 300blk game.

I can't do it "right" yet as I am still waiting on CA SBR permits (01/03) so this is a CMMG 16" barrel, piston gas system.

Got a loading setup going, single stage LEE press. I am chopping my own 5.56 brass, getting pretty efficient at it.
My first load was 220Gr SMK with 10.5gr of 4198. Don't have the chrono going yet but these were definitely subsonic and cycled flawlessly through the rifle but suppressed and unsuppressed.

I am running the 7.62SD can and WOW these are quite. Still need to test for accuracy as all I did so far was a function check.

I'll have some more tests up soon. Water jug tests coming soon and I will load up some supersonic stuff.
