Old thread but another range day. Decided to shoot up that 1975 Indian Army surplus I had left for 98's lube test. Nice excuse to blow through 180 rounds. Forgot how satisfying a mag dump can be. My AR10's are sighted for 168 and 175 gr reloads, so it took a little bit to dial in with the old Indian surplus. The stuff was amazingly accurate. Someone had stuck a dozen clay pigeons on furring strips stuck in the ground. I was exploding the pigeon on the first bullet, and snapping the stick at the base on the second at 100 yards. The AR10's were flawless. About 20 rounds in, and I could not miss. After I was done I was wishing for another 200 rounds. Just an enjoyable day. Now I have a bunch of brass to load up with Sierra BTHP's, and a renewed appreciation for my AR10 B's love these rifles!
