OK...All is better now. I just ran a 25 round string @ 76 degrees, 1600 ft. altitude and zero wind. The SD was 9.8 with 2936 as the average speed. This tracks pretty well in my mind. This is factory Hornady Match 6CM 108g ELD ammo. I have NO idea what powder is in it. I'm done finito never again bumping shoulders, turning necks and all the other stuff that goes into true precision round hand loading. I'm older and I can buy this ammo at will. Don't ask me how. I can't shoot well enough to NEED better ammo IMHO. I'm shooting just three PRS matches this year and one is already behind me. I do this for fun and to keep my sanity in todays world lol. It's nice to know I can, on demand, shoot something at 1000 yards. Thanks for the input/help guys. I really enjoy this sport and I'd like not to embarrass my son with my shooting.
