I think Moe summed it up pretty well.
I've only put about 300 rounds through mine, and have handloaded for it. If you are looking at surplus or bulk ammo I would try the heavier 62 gr bullets, the 1:7 twist barrel should stabilize them better than the 55's. Troy says not to use steel case ammo because it could damage the gun. I believe they are concerned that it may not contract as much as brass after firing and get stuck in the chamber. If mine has a fluted chamber I can't tell from the brass, there at more no marks on it after firing.
All around it's a great gun. Due to the endless possibilities for reloads, I'm still testing, but so far I think the gun shoots well for what it is, averaging just a tick over moa at 100 and 200 yds. A load I recently tested at 300 yds produced a 10 shot group that was 4.5" without allowing cooling time for the barrel. I'm happy with that.
The only functional thing I've done to it is some trigger work, it was a bit gritty and had too much creep for me. After polishing the sear and installing a set screw to remove the creep, it's much better (thanks youtube). For $250 a drop in trigger would be even better, but I'm cheap.

The only other change I would consider at this point, is rebarreling to .277 Wolverine to buck the wind a little better and send more energy downrange for coyotes.
