I took my Bog Boy to the range today. It worked well except for an occasional failure of the next round in the magazine to slide out and into the shell lifter. All I had to do to clear the problem is pop out the empty case with my finger, put the bolt back into battery, and then cycle the action a second time. I put 50 rounds through it, and it did this 1-2 times per magazine full.
I am hoping this is a break in thing.
I cleaned it well, removing all the factory grease and what-have-you and lubed it up with Ballistol. I haven't tried running ammo through it yet but it seems to work more smoothly having been cleaned of factory grease.
