From remembering, ARP chambers a little tight.
ARP mentioned about the diameter of the Hornady AMAX cases. They said I could ship the barrel back and they would polish the chamber.
Hornady SST will fully chamber and bolt locks.
I didn't fire it though. To get it to manually eject needed some extra assistance = it was stuck.
I measured the cases and sure enough, there is a 0.0005" difference through the entire taper between the two cartridges. (measured at several radial locations along the 2 casings). Not a large value, but that is making the diff between chambering and binding with not allowing full chambering.
At this point in time, I think it will be fine with a chamber polishing.
