I found 308AR doing a research on a my new rifle that a friend just build for me. The rifle is a DPMS platform LR 308. Last Friday I zeroed the beast, it was great. This forum has answered most of my questions by just reading the posted, very informative and educational. <thumbsup> Thanks to all.

Hello I'm new to the forum, reason for becoming a member is I'm having a AR-10 build. Is there a difference in the ballistics in a Rd's of 147gr to 175gr from a 18inch barrel of a carbine and a bolt action 22inch? at a range of 400 to 600meters? Thanks
