.300 blackout data?

.300 blackout data? - 11/28/17 11:11 PM

Does anyone have good load data for 110 grain Barnes TSX using H110? I am running 19.6 grains of H110 and getting about 3250 FPS and decent groups, but wanted to see if anyone is pushing them faster with great accuracy?

I use 20.2 grains to yield just over 2400fps and good accuracy in a 16" gun, no way are you getting 3250 in a 300BLK.

You can certainly go hotter than 19.6 with a 110 grain and H110. If you are running 223/5.56 brass cut down, the max charge will be less than 300 blk out head stamp brass, as there is more internal case volume. I'm running a 115 Berger at 2370 fps in a bolt gun. The 110's run about 2400+.

Yes, I was typing too fast and mistyped the FPS. I just wanted to see what the max velocities I should be able to hit before any pressure and accuracy issues. I am loading all .300 blk head stamp brass and shooting out of a 16" AR.

I was just getting nervous about exceeding 20 grains due to it being the max load in most manuals I've looked at. Looks like ill work up some loads from 19.8-20.2

^^ That will work. 2370 fps is the speed I'm running in the AR. It's 2450 fps in the bolt gun.

^^^^ That's a good load. I have been happy with 20.2 of lil gun too.

I load mine with 20.1gr of H110 for my 10.5in 300Blk. I also use the same load for the 110gr Vmax. No pressure signs at all in my gun and I am using .223 converted brass.
