300 Blackout Finished

[MED]

My 300 BLK pistol is my favorite thing ever. Accurate 5744 with 150 grain @ 2000 fps is my load.

Have you used this load with the surplus M80 147s? ...which projectile do you use?

I am still trying to figure out what I want in terms of loads. I am going to try the Lucky13 polymer coated 123gr with 16.8 of IMR4227 (should keep the velocity down). If this load works, it keeps my cost down to $3.25 a box. I have five hundred Speer 125gr TNTs to try as well along with three pounds of H110. I haven't picked up any heavy bullets yet for subsonics, but I have four pounds of AA1680.

I have another 300 rifle build in process with the Mag Tactical lower and 16" barrel.
