I have an 1148 410 with feeding problems. Hard to figure out. Can't get rounds past the carrier latch, and when I do, they will not come out when the action is cycled. The carrier latch is protruding over the magazine. It seems the follower is holding the back of the carrier latch from coming over. With the shell latch removed, the carrier latch operates properly. All the parts look good, everything else works fine, locking block goes into battery, etc. Any help is greatly appreciated!
