Never been much into shotguns but recently picked up a Marine Magnum. I compared it to the Mossberg and the Remmy just felt more solid. I went with the Marine because I can be sloppy and dont want any chance of rust. So far I love it but have only shot 2 3/4 inch birdshot shells a buddy gave me. Im not int trap shooting this thing will be for defense, likely carried in my truck when traveling and in the closet by the bed when at home. Suggestions for cartridges would be appreciated.
