Just got my AICS 10rd in the other day so naturally i wanted to try it out and see how everything worked. Some rounds feed fine others seem to be angled down after extracting the previous one. When the bolt pushes on the rim of the case it pushes straight into the magazine wall causing a jam (kinda like a regular 700 floorplate does sometimes) then i can just slide the round back and it will come up right in the magazine and feed fine. These are loaded with a COL of 2.810 so nowhere near max OAL from what i understood.
