I'm personally torn on the Axis vs 10/110 action.
The Axis was a production cost decision. Simply the Axis is cheaper to produce. That said, the Axis action is similar to the 112/12 Palma action which has proven that both are stiffer than a standard 10/110 action. This should produce a more accurate platform similar to a short action vs long action. The short action is supposedly more accurate. The Axis/Palma actions are supposed to be stiffer and therefore more capable of producing better accuracy.
I can't say personally as I have only built on the older style action.... but I'm torn on which would be better in a new build.
I have built rifles on older style actions including the medium "J" action and all have been shooters. (short and long)
If the price was right I wouldn't ignore the Axis.
