Ok, but if you are attacked by a grizzly while you're looking for turkeys, I doubt you'd have time to load the slugs and the bird shot is going to make him madder than hell.
I'd rather take my chances with my .243 AR10 carbine with 20 rounds. My thinking was to have one gun and one load...for everything. However, It'd be best to not get in that one gun predicament in the first place. A better idea is an AR10 in .308, a AR15 in .223, a .357 revolver, a .45 1911, and of course a 12 gauge pump.....and I will as long as I have a vehicle and gasoline to carry them in.
