just to clarify I'm not bashing shotgun use at all .. as you can see I have my bad boys right here but they are not loaded with no bird shot (buck and slugs), and you'll notice they are kept right next to the AR10 in 308 and the AK
shotgun is super effective with the proper training and proper loading and ammo choice as well as the choke selection.
a random Walmart shotgun with some 2.5 no.8 bird shot is not the best choice imo.. ain't no soldier, swat, or terrorist, etc.. carrying that into a life protecting battle. . not sure why so many citizens have been dooped into thinking thats what they should get when their life depends on it
