300 Blackout Subsonic loads
Posted: Fri May 22, 2020 3:13 pm
I have been reloading for my Ruger American in 300 BKO with a 30 cal suppressor keeping the FPS in the 1000-1050 range to stay subsonic of course. Curious if anyone else has worked up any loads for the 300 subsonic?
Right now I have seemed to have settled on 9.3 grains of H110.
I had been using Hornaday 208gr A-Max bullets, but now I switched to their new 190gr Sub-X.
The Sub-X is I believe the first bullet made to expand at subsonic speeds for this cartridge. It will expand going as slow as 900FPS where as the A-Max, needs at least 1600FPS to expand.
I dug a few spend rounds out of my dirt backstop and as you can see the Sub-X is as advertised. Check out the pics.
I would like to here about anybody else's experience with 300 subsonic loads!!
Cheers,
JAY
