My browning magnum 12 gauge shotgun is jamming--it is not ejecting the chamber shell?
The gun is probably set for heavy loads with the friction rings,
and the loads are too light. Remove the forend. Inside the wood
forearm may be a diagram to show how the bevels and brass friction
ring should be set for light vs heavy loads. If no diagram, go to
Browning .com and there you can find a diagram, but remember to
find the Mag 12, it is different from a standard A-5. When shooting
heavy 3" loads, set the rings to heavy. When shooting 2 3/4 lighter
loads set for light.
