With a google search I found very little other than send it to the factory. They will not accept the rifle as i made a few mods to it. What i do know is it started life at Wal mart where i bought it for $214.00. It had the same problem I have now. Light primer strikes. The first box of factory ammo was fine. however the gun had a hard bolt lift. I loaded up Lapua large and small primer loads. Same deal. I cleaned the bolt assembly and somewhat better results.

My thought was bad chambering, bad bolt internals or ? I looked though all 4 pages of the axis threads with no fixes. I can do some machine work or will pay for the proper fix.

Here is a pic of the chassis I built. The bottom piece is an AICS mag extension. Chambered in 6gt with a go gage and scotch tape with slight drag. Criterion barrel. And no I didn't check the case to barrel dimension as I just read it tonight.
