Now that 20's are around, I think this would make a great little Scout/utility rifle in stainless with the Hogue stock, Ultimak rail and pistol scope or red dot (or conventional compact scope, 1.5-5x), maybe a vortex/phantom/surefire/other flash.
I learned to shoot on a Mini and could see the above described 6.8 being my ideal go-to for anything centerfire, many 'cooler' options out there but nothing would feel as at home, I think.
Don't know much about this chamber issue, but will definately be watching for an updated model. All I was waiting for was a high cap mag, otherwise entertained ideas of a 6.8 or 6.5 Grendel on a extra-short action turnbolt. Would be cool if they brought it out in the tactical format like the new 14's with the 16" tapered barrel and factory flash hider, winged front sight at mid length and the Hogue stock. With factory 20's it would be kinda irresistable as a practical using/working gun.
