[QUOTE="shortgrass, post: 383624, member: 24284"] Here's another thought for the mix. Ackley Improved [I]head space[/I] is shorter than the parent cartridge. When you cut an A.I. chamber the [B]go[/B] gage becomes the[B] no-go. [/B]Ya' cann't set the barrel back a turn on an AR. You would have to start with an unchambered barrel and chamber it for the A.I. Your barrel is 24" w/1in8 twist, most likly S.S. If it happens to be a chrome moly chrome lined you would need a carbide finish reamer as that chrome lining will, certainly, dull a H.S. reamer and won't cut the chrome, not even for [I]one [/I]re-chambering job.
