58.08mm OAL for both rifles, but for the 20" gun I have to pull it back to 56.9mm to eject a loaded round, due to it not clearing the port. I could fix this with a minor mod to the ejector / bolt stop but just left as is for now. Have over 200 75gr loaded to that OAL.
These Sierra 85gr HPBT are a stubby nosed little bullet, just like the 75gr HP, they lend themselves well to short mags and OAL.

Ta. So they will fit into pretty much any .223 mag then (Tikka is 2.3"/58.42mm).

Do you know how fast the 90gn Sierra's are going ?
I have a 200 of them to play with , but thought I'd start with the 85gn Sierras because of the great reports from overseas about their on target performance
