Re: FMJ's on coyotes
I have shot coyotes at 300 yards with 55gr Vmax bullets into winter fur, and they have run more than 100 yards to the property line and kept going. I don't doubt that they died a while later, since they never did come back.
What bullet to use on a coyote is mainly dependent on the reason for killing the critter. If you expect to make money off pelts, then you will want high velocity light weight bullets like the Vmax or similar. If you simply want to kill them, pretty much any bullet that is carrying enough energy will do.
As another writer has said, Match bullets or VLD's will extend the killing range of about any rifle, provided it can shoot them right. I currently only use 75gr Hornady HPBT bullets in my 223 and 95gr Berger VLD's in my 243AI. Since coyotes are the only thing I legally get to shoot at with a rifle here in SE Michigan, I figured I would up the game to my 8x57 shooting 196gr FMJ or match bullets. Now it looks like it will be a 308 shooting 175gr SMK's for anything closer and the 243AI shooting 105's for anything farther/more wind.
I do want to spend more time behind a heavier rifle to prepare for wolf hunting out west, and the coyotes are going to end up dead whichever way. I will probably keep my DAG 147gr battle packs sealed up as "iron reserves" and use my reloads with the 175 SMK's for everyday use.
