I have been having the same issue as the OP. Sometimes the bolt will not engage the shell, other times when it does (and I'm talking pulling like a natzi), the bolt will have to be pulled back a little to get it to feed into the chamber correctly. It is a pain, and I am reconsidering taking it out after caribou next month.
I have fooled with loading the shells a bit forward, which sometimes works. Also, one has to be really careful that the magazine is all the way in... even if it looks like it is. Having been a big enthusiast for the Edge/Axis (I own one in .223 also), I am beginning to feel a little disappointed and apprehensive. Anyone else have this problem?
