Yep, got a VCC contour 7 Mag barrel, #3 7 PRC barrel and M24 300 rum barrel for mine. I've only been able to shoot the 7 Mag and 300 Rum and the action handles both easily. Had to play with MDT mags to find some that work with each caliber, but once I did, no issues. Waiting on 7 PRC dies and brass to hit the market to try that one out. Both the 7 Mag and 300 Rum barrels lock up as they should and return to zero when removed. Makes for easy cleaning too.
