My Marlin 336c in.30-30 is the go to rifle for gun hunting right now. It has a Ghost Ring rear sight and a post front sight which I replaced the dovetail and hood sights for. I like the rear site closer to my eye. Last year I shot a 4 point blacktail running right to left at about 20 yards and dropped him with one shot (that'd be a 8 pointer to you whitetail hunters), a 3 point blacktail at about 80 yards standing broadside, and a nice hog at 100 yards. Dumped all three of them. 6+1 capacity gives a decent amount of shots available. Just a good, solid rifle.
Don't know anything about Mossberg.
