Rifle is a Barrett 82A. If anyone could give me a link to some graphed load data (for 640-820gr projos?) that I could print and put in my reloading book I would really appreciate it. I have a membership on FCSA, but I can't seem to find any decent data for the pull down powders on there. Thanks!
I have used loads between 220-225 grains for AP,API,APIT,Tracer,and Blue tip. With 225 grains of 5010 and AP projectiles it made the bolt a little stiff to open on one of my rifles but not the other 5 rifles. I used 170 grains of 5010 for the Spotter/Tracer projectiles and they shot well out to 2200 yards. I know others that have used 180 grains of 5010 for the spotter tracer, but I would not go much higher than that or you may have one go off in the brake or just outside of it. I loaded up 1600 rounds for a fun shoot with all surplus projectiles and loaded half with 222 grains of 5010 and half with 222 grains of 860 and they both shot well shooting 200-2200 yards.
Be carefull with the new 5010 it is a lot hotter than the old stuff I have been using. You may have to go as low as 200 grains from what I have been hearing. I have not tried it yet myself, I still have plenty of the old stuff on hand.
