Was able to shoot between rain fronts today and the chrono was working good. This is the 11.9grain load with N120.

Average fps: 1181
ES : 37
SD : 12.5

100 yard groups ran around 3/4" this load groups better at 37^F and lower

It was 54 degrees so the velocity ran higher than before (avg. 1050fps). I am going to test 10.9grains in warmer weather to check velocity.
One ragged hole! The quest for accuracy continues...

I found some success at last with the hornady 190 subx. my gun is noveske 14" pistol gas and the load that shot 1" in 10 shots was 10.0
shooters world socom powder in factory pnw brass that have cci 41 primers. ( or so that is the primers they said were in them.) very quiet ,
no unburned powder and cycled great and very accurate. I am going to try it with lc reformed brass and different primers to see if I can fine tune
it some more.

Has anyone found the max load these bullets will shoot without coming apart after leaving the barrel?

Also interested to find this out. Wonder how these would shoot in a 308 win.

Any reason A1680 isn’t the go to powder for this bullet? Seemed like that was the powder everyone was using for subs.

It’s loud when you want to make subs quiet. I call it Thunder Powder. But it is damn close to a sure thing for cycling subs in ARs.
