Hi folks... I recently acquired a Mossberg Security 7+1 12 gauge shotgun from big 5. It says in the manual that I can use 3" shells, but I've noticed that 80% of the time it doesn't eject the 3" slug shells I've tried. I have to fish them out with my fingers. It seems like the slot is just too small for the shells when their "mouths" have expanded an extra 1/4" after firing. Is this normal? Is there another type of ammo I should try?
Thx!
