This isn't constant but it's like the round is sitting to low in the magazine and the bolt can't reach.

This doesn't happen every time nor that often but can it be fixed?

Check to make sure the interrupter is moving freely. You can also replace the mag spring and follower. Its possible that its just because the spring is ancient.

Also, how are you loading the magazine? Especially how do the rims stack up on the cartridges?

I agree with the above.Try bending the mag spring to put more upward pressure on the rounds.I had an M39 that had some feeding issues like this and it helped mine 100% by bending the mag spring.

Check interrupter operation before bending anything. The interrupter may have wood shavings and or cosmolene built up around it binding it up. Rim location makes no difference once the rounds are in the mag. The interrupter allows the next round to "pop" up away from the other rounds in the mag for feeding. Rim location is important when loading strippers for ease of insertion into the rifle. Two of mine had this trouble and all it required was a little more cleaning around the interrupter to fix.

The interrupter is where?

Inside of the receiver, right left side. It acts as the ejector too.

The mosin mag box holds the top two rounds separate from each other, and from the remaining three. If you put 1 in and push it down alittle deep it will take two complete cycling of the bolt to bring that round up.

Is the interrupter the little spring-loaded doohickey that pops out and prevents rounds in the magazine from rising? Because that stupid thing prevents my mag from feeding half the time I load my M91/30. I have to reach in with a screwdriver or pocket knife to push it in so the round will feed; after that, it feeds fine.

Yep. Either you have stuck cosmo/gunk or you need to bend the spring to exert more pressure.
