.308 Sub Sonic Loads - 09/27/11 09:14 PM
I have been researching a few good loads for my .308, I have a suppressor and I wanted a nice mouse fart load! I started at 11.0 Grains of Trail Boss and worked my way DOWN to 9.0 grains. The 9.0 Grain was not accurate and didn't stabilize the bullets even at 50 yards.
Here is what I came up with:
Lapua Virgin brass
BR-2 Primer
10.0 Grain of Trail Boss
170 Grain Round point 30-30 bullet .308 diameter
2.685 OAL
Very Very Very quiet and accurate out to 100, easily shot sub MOA at 50 yards and about MOA give or take at 100 yards.
Oh ..here is a video comparison. The first round is a full house Southwest Ammo 155 grain palma load that is 2900FPS @ the muzzle! Scootin! The second shot is a mouse fart sub sonic.
Rifle Specs:
M40A3 Clone
Schnieder 1-11 twist bbl Cut @ 23.5 threaded 5/8x24
Mcmillan A4 stock, with adj cheek piece sniper fill
Rem 700 action trued
Rem factory trigger (non ex mark) tuned to 2.5lb
Badger M5 bottom metal
