buy a 870 or 500 cheap enough to see if you really want to justify the expense of a semi auto shotgun and if you don't like it you can either sell those or turn them into home defense guns, honestly I like to shoot trap/skeet but it gets boring to do it after a while. Any one can easily bust 90 percent of what they aim at
Brian 249 is the 5.56, 240b is the 7.62 carried in a weapons squad still in use by everyone today. I haven't got to try to lighter version of it, seems like most of them are getting used by people who are deployed
