AR-10 in .284 Win?

Re: AR-10 in .284 Win?

A friend who is a High Master X-course shooter built a 284/M14 about 20 years back. He made a LOT of mods to it, but it did as well as any bolt gun at the tme. That being said, The 284 can achieve a LOT of pressure. An gas gun can't take that kind of pressure, so you need to load it down to around 7mm-08 velocities. so you may as well go with a 7-08 f you want a 7mm.
