Hi all, been a while since I have posted here. I just put together an AR in 7.62x39. I've got some brass and some cfe223 that I'd like to use to work up a deer load for my sons. I'm thinking lighter and faster as opposed to heavier and slower but im open to all the good ideas and experience that the lrh community has. Have done some looking and found some 10 year old threads with this case and powder so I thought I'd revive the campfire here and see if there was any new data on powder and bullet choices. Thanks in advance for the advice.
