Trying to duplicate 168gr Black Hills Match ammo for my DPMS LR-308B. I “hear” they use Ramshot's Tac powder and Sierra 168 Mks. That's the same combo I'm using. Advertised velocity is 2650 FPS, but they don't mention what gun they used. I started at 39.5grs of powder and in half grain increments, went to the max of 42grs on the Sierra chart. None of my loads are as accurate as the BH loads. Some are close, but just not there. Could it be the mixture of brass I'm using? It's a combo of different years of LC with some Winchester and OFV thrown in. You can see some results here: http://www.pixagogo.com/9751124271 Granted conditions were not good that day and the particle board blew back on some of the targets making measuring groups hard. These are 10 shot groups shot at a half inch square. Any ideas?
