.300 Blackout Load Data

[Ivan Smythe]

Just purchased a Rem 700 in .300 Blackout with a 1 in 7" rate of twist. Bought 2 boxes of the Hornady 208 gr AMAX @1020 fps and 100 pieces of virgin brass.
I am interested in the sub-sonic loads with the heavier 200-240 gr bullets.
Anybody have any load data they care to share?

Thank you,

I.

Hodgdon's site goes up to 230's. Includes the 208's and 220's. Listed as .300 AAC Blackout.

for it,s with A1680 i have the best result for subsonic loads
works well with 208 210 215 225gr and cycle well in my AR-15 without modification

Bolt guns and AR's are 2 different things. Yes, you can use the AR based load data to shoot in bolt guns. That's a good start. However, do realize the powders used to make cycling in AR's reliable are not going to make the quietest subsonic rounds in bolt guns. For that, you're going to want too experiment with faster burning shotgun and pistol powders.
