I use a rem 11-87 full choke and shoot #4 buck 3in shells with 41 pellets I can roll 1 at 50-55 yds The r about 5-6 dollars for 5 shells. If you have deep pockets Dead coyote shells are the best but they are 10 shells for 35 dollars but are more lethal then the others

i have a savage single shot 12ga full choke and i can easily put down a coyote from 75 yrds with double ought buck, i've taken out deer at that range with double ought buck so a coyote shouldnt be a problem at all.

this is a good shot also.

I shoot a 870 express supermag 12ga and use a full choke with 000 buck for totes

Full choke / 4 buck = dead yotes (good shots) !

If you can get ahold of any #2 shot it is pretty nasty on yotes. I don't like 2 3/4 inchers though I like 3". You can reach on out there with a good full choke. BB

3" #4buck pattern master extended range benelli SBEIIworks wonders on them wen we hunt them with dogs

most importantly pattern your gun as stated before. Use lead shot no smaller than BB and no larger than #4 buck you could go bigger but why? BB's to #4 buck will do the least pelt damage and will kill them fine. If you want them DRT shoot'em in the face.

better check your state regulations in some states it is illegal to shoot buckshot at anything but targets or people,for self defence I mean

I use a 2-3/4" at night and Winch. Supreme #4buck with a Pattern Master choke. It is DEADLY out to 40 yds. Even though I back it up with 3" ammo, I don't get to it very often. Daytime is another story. 3" and 3-1/2" daytime!!!
