Rye, what kind of feeding problems?
Ammo won't go into the chamber? Check your crimps, and chamber mouth, the chamber lips should have a slight roundness to them to help smooth feeding.
Is it when trying to close the lever? Review OAL of ammo, and there should be a ramp type cut into the frame right about the backstop on the loading gate. Sometimes 38s, and get hung up there a bit and cause a hiccup when cycling the action.
Bottom lip on the bolt proper length and such?
Or maybe you just got Gremlins, of which only real black can scare away.
