Coyote hunting with .223 remington?

All of these 55 grain rounds will impact close enough together to do the job on a coyote within a couple of hundred yards.

The ACOG will work fine for coyotes at a distance, it's -not- that great for close range work... People are thinking of the Aimpoint. If you have an ACOG with the common 3.5x or 4x magnification, it will work fine at medium range.

In many states coyotes aren't considered "game" but varmints and if you want to use FMJ, they may allow it.

I build match AR-15's.

I am also a long time Alaskan hunter, trapper, and former military long distance competition shooter.

Nearly all factory 55 grain bullets have the same, or very very close, ballistic coeficient - and because of this they all hit in the same place at 100-200 yards. Even handloads, so long as they have enough power to cycle a semi-auto - will hit in the same place.

It's not until you move beyond 200 yards that different loads start t show what they are made of. You have a Trijicon Acog - a firearms sight designed for doing dynamic entries and CQC (close quarters combat). This is probably the most totally useless thing you could have mounted on a varmint hunting rifle. Even if I handed you my best handloads that incorporate my 35+ years of reloading experience - any 6th grade kid using rounds found in the dirt at the range will out shoot you at 200 yards. Point of Fact.

For coyote - you should be using a scope similar to the BSA 'Sweet 223' - For $97 it will let you hit small rabbit sized target from 50-400 yards easily. Your expensive Acog is designed for people sized targets from 7-50 yards.

You have much bigger issues than different bullets my friend.

Coyotes are fairly small game and most guys use anything from solid lead ball bullets (no jacket) to jacketed hollow points in 40-55 grain. Long range (over 300 yards) you would need to move up to a 6.5mm or larger to have good terminal velocity at the target. Good Luck!

FMJ shouldn't be used for hunting. They're more or less designed to give the highest survivablity rate of any round out there. Whether or not your vmax will hit the same place, maybe. Some rifles put rounds in about the same place regardless, others will have a different POI. Try them out on paper 1st, then go hunting.

The ACOG is not meant to be hunted with, by the sound of it you built a CQB weapon not a hunting weapon. In many states, FMJ ammo is not legal for any type of hunting. Go with VMax, Barnes Varmint Grenades, or Nosler Ballistic Tips.

I don't know that it matters a whole lot which round you use. You should double check your state laws to make sure that it is legal to hunt coyotes with FMJ. I can not imagine that a state would outlaw FMJ for coyote hunting. You can use solid lead .22 LR in most states.

I bet all 55grain bullets you run in that AR should be minute of coyote

IIRC an AR "zeroed"at 25 yard will deliver all hits in a 9 inch circle past 200 yards

I'd sight in for the vmax, just to be safe, full metal jackets are usually illegal to use on anything bigger then a prairie dog,

Try the Vmax.I think they wont exit and damage the pelt(if youre worried about that).FMJ might let the yotes suffer.

It is such a high velocity round that the hydro-static shock will mess them up. You should shoot both just to make sure.
