Follow up shots... what is the cover like where you hunt? If the cover is dense then good follow up shots aren't gonna happen as often as you think. A missed coyote is just a split second and a jump or two from being out of sight and your emphasis should always be on an accurate high percentage first shot. If the country is open, then you have a considerably better opportunity for an accurate follow-up shot in case of a miss.
I hunt heavy timber and tried several bolt guns, the AR platform, then a Browning Lwt. Synthetic BAR, and have settled on a pair of Benelli M1S90 12 gauge semi-auto shotguns for much of my hunting. I did this because the rifle just doesn’t work out as well in much of the thick timber and brush in this steep Ozark mountain country. Under 50 yards the shotgun simplifies things and is very decisive.
The AR seldom sees the field anymore. I still use the BAR some, but now more often than not if I’m using a rifle it is an accurate Remington Model Seven Predator bolt gun and I really focus on that first shot because I know there won’t be a second shot if I flub the first one. The bolt gun is lighter, slightly less bulky, and has a better trigger. Not much difference really and I can use either and like them both, but the point being second shot opportunities may not be as common as you think depending upon cover and terrain in your hunting grounds.
