I'm shooting 28gr of IMR XBR 8208 with a 123gr sst, 2365 fps avg out of my 14.5" barrel and scary accurate. I doubt I'll change that load out any time soon.


Here is a 12 shot 100yd string, 14.5" Sabre defense CL barrel, standard AR trigger, bushnell AR scope. ~1.25" with above load prone with bipod mixed headstamp brass. The next 10 shot group opened up to 1.75", either me or the barrel was getting warm since I shot 20 rounds without stopping whistle .
