Found a sweet spot at 30.6 grains CFE223, 2.230 coal. 2550 fps out of a 24" Radical Firearms upper, JP bolt, ALG trigger(modified) ALG handgaurd. RP 7.5 primer in once fired Hornady brass, trimmed and chamfered. Slightly less than 1.2" center to center. Now to try different seating depths, and a base to ogive tool soon to be inbound. Started at 30 grains even, every .2 grain increase resulted in a 20 fps gain in velocity. 30.8 grains, no increase over 30.6. Every group shot with this barrel always has 2 touching, with 3 outliers. 30.6 had 2 groups of 2 touching, with 1 outlier making it 1.2 inches. Extreme spread 34 fps.
