I have been working on this for years It seems to me a good comfortable sling around your chest with a folding stock or a hand grip works the best .if its in a case you cant get it in time+it takes a beating on the sled I prefer a 18 or 20 in. barrel loaded 00buck, 00 buck ,slug more if its legal. this is fast +deadly as you can shoot on the move. if you see them way out there all the time, use a flat shooting cal. in a lite+short rifle with a good scope. rem. model 7 in 7-08 works good for me out to 600 yds. put a peice of tape over the muzzle so snow wont get in you can shoot through it if you have no time to remove it. in Can.I would think you can get out where people dont go? Be sure to remove gun oil fron all working parts fireing pin, bolt,hammer+trigger ect. gun WILL get wet+very cold on a sled, I have had many that would not fire when the time came. use wd40 or graphite, if you do carry a handgun autos work much better in the cold+do NOT put it in your belt use a holster on the belt. or they might start calling you one NUT. coyotes are TUFF!!! yesterday I hit one twice between the skis at 75mph he rolled many times then ran over a fence+got away, no gun with me. bring enought gun+if anything can go wrong it will, they dont call them WILEY COYOTE for nothing! I hope this helps good hunting.
