I went and bought a .50 BMG upper ... while I am waiting on delivery, I'm working up some loads for it.
Has anyone done anything with 690 gr bullets and WC870 vulcan powder? I know Serbu is selling .50 DTC rounds that have 220 grs under a 720gr bronze projo, so I have a starting point ... but if anyone else has worked up a load, I'd like to hear about it.
