I had amazingly good performance on coyotes with the 40 gr Nosler Ballistic Tip. Seems to kill them faster than the 55 gr version does, but testing continues. If you want a bigger tougher bullet, the 65 gr Sierra GK and the Nosler 64 gr Bonded Solid Base might be what you want. I've tapped a few medium sized pigs with the Sierra, but have no actual use info on the 64 gr Nosler (yet). I don't deer hunt with the 223, but if I did, I'd use one of those bullets.
Just to mention it, I did use that 40 gr Nosler on some 60-odd pound pigs. Shot them behind the ear and they went straight down. Wouldn't have been my first choice of bullets, but that was all I had with me at the time.
I use H335 behind all of the bullets mentioned, but AA2230 worked great behind the Sierra in my first barrel on the rifle. Primers are CCI BR's.
