So I just bought an AR in 300 blackout with a 1:8 twist, pistol length gas system, and adjustable gas block. I want to load the Lee 312-155 water dropped wheel weight, gas checked with Felix lube. I want to load super sonic loads for this.
From the immense amount of reading I have done on here I think I have settled on H110 for my powder. However I'm on the fence between it and lil'gun. Thoughts?
My main question is with annealing and seating depth. For annealing the brass which is apparently a big part of good accuracy with this round would it be dumb to anneal the brass just using my electric coil stove top? I tried it once and it seems to work. I really don't want to blow a lot of money on map gas and propane tourches. I have a source of free 223 brass so I'm cutting and forming my own.
For seating depth does any one have a good medium between function and accuracy for that depth? There isn't a whole lot of cast data that I can find for this round so I don't want to seat too far in and cause excess pressure issues.
