I've only loaded two powders for my 6.5G, BL-C(2) and CFE-223. I'm sticking with the CFE. The loads I took to Bangsteel was 31.5 grains CFE-223 and 123 AMAX, and according to Dan's ballistics program, they would still be supersonic at 1175 yards at our altitude and weather conditions that day. My chrono data with these loads gave me 2560 +/- 3 fps on the 20 rounds I measured, in a 20 inch 1:8 Odinworks barrel, semiauto action (AR15). I have been getting consistent 1 MOA groups out to 300 yards at my local range, and they seemed to hold no more than 1-1/2 MOA at 1000 yards, considering the percentage hits I was getting on 18x18" steel plates at that distance.
I took a small batch of 123 SMK's loaded to 31.5 grains CFE-223, and shot them at 500 yards after shooting the AMAX loads. Using my AMAX zero, the SMK's hit about 1-1/2" higher at 500 yards. I would assume the fly a tiny bit flatter than the AMAX. I've got a box of the new Hornady ELD 123's, and I want to try the 130 gr. Tipped MK's. I'm hoping the very nice BC of those might at least partially compensate for a slightly lower MV due to lost case capacity. At any rate, I'll stick with the CFE-223 for all my loads.
