AR-10 build for speed (220 Swift or 22-243)

[436]

As in the 30 rem AR or a different cartridge? That would work in a 15 platform and have some speed for sure..............well according to QL

When I built my cartridge based on the .30 Rem I shorted it for the AR15, not the AR10 this was way before the 6.8 SPR came out also based on the .30 Rem case concept, I was going to make up 6mm GTO but never got around to it, how time flys. But the long case concept and the AR10 would be very entering, to say the least, I see a lot of possibilities in it. Back then I used a .22 cal 90gr flat base bullet. I tested in a M700 that I reworked, but later it went in an AR15 Actually it looks and performs more like today's .22 Valkyrie although I think it could have edged the .22 Valkyrie out a little in vel's. The 6mm version might have been a meat axe from an AR with little to no modification. Cheers.

Look up Specialized Dynamics, they do a bunch of hot 22 cars including the 220 swift
