Ar-15 for coyotes
 

I got an Sun devils© Ar-15 .223/5.56 for christmas and I want to go coyote hunting with it and want to know what bullet type and grain weight is best. I plan to sell the furs.

Honestly it depends more on the gun than the intended target for grain weight. What is the barrel length and twist rate?

16 1/2 " r•o•t : unknown

I'd go with either Hornady's 53 grain V-MAX Superperformance or their 55 grain V-MAX.

Twist rate should be stamped on the barrel somewhere. 1:7 or 1:9 most likely. This will impact the ability to stabilize the flight of your projectile and choosing the correct weight of projectile will matter if you're trying to make a clean hit on something as small as a coyote. If you have a 1:9 twist, you might be OK with those light bullets, but if you have a 1:7, you will want a heavier bullet like a 68-69 gr. HP.

If you are going to sell the fur you had better use FMJ or the buyers won't give you crap for the fur. Now this guy we use the 338 on!!!http://i1063.photobucket.com/albums/.../BigSpider.jpg

I have some mil-spec 5.56 fmj. I think military ammo.of this caliber is somewere in the 60 grain area. are those effective/ethical for coyotes?

I am assuming boat-tailed.

As long as your shot placement is good, I see no ethics issues.

I use American eagle varmint works great and if u can find it it's around $8 a box of 20. so it's not a expensive ammo well it mite be now tho with every place being sold out
