You need to be in the 110 forum. This is the Axis forum. The Savage 110 & Axis are two different rifles sharing several parts like the barrel & nut, but are different Actions altogether.

To start, what cartridge do you have? Is is 6.5 Creedmoor or something else? Are you speaking of changing to the AICS 10rd mag or the Savage 10rd mag? Yours has the little plastic tab release on the front of the magazine, right?

This is the easiest way to have a 10rd mag.
