40's bleed off velocity very, very fast. This means that wind blows them around like a kite.
I shot them at 3800, and at 300 yards coyotes did not go down if not hit perfectly, 40g Nosler ballistic tips in a 26" custom 223, with zero freebore using N133 and cci br4 primers.
60g Has the trajectory of a 45/70. A guy that wants to go 60g in a 223 because of distance, he would be better served with a 22/250 or especially a 243.
This was my experience shooting coyotes that were out in irrigated fields trying to catch gophers that were trying to escape the water. I had a lot of shots from 150-350 yards, my rifle was sighted in at 200.
I found the 40g Nosler and 40g Sierra Hp to be exceptional at close range, past 150 sucked hind tit. You have NO grace shooting 40 grainers if you hit them behind the diaphram at 3600, and waiting for coyotes to stop running, trotting, just does not happen all the time. Shooting at moving coyotes means you have to leade them, and due to trial and error, you will hit them all over the body, including the hip joints.
For those that like warp speed and a slightly tougher bullet, you should try the Sierra 45g spt, which is a high velocity bullet that WILL penetrate bones! I killed a lot of coyotes with the Sierra 45g spt in both the 222 and 223, but the magic started in the 22/250 and 220 Swift with this bullet, usually in the 4000 pfs in the 22/250 and 4200 in the Swift, with AA2700.
When the hides were worth good money, I shot a load that was simply unreal in it's killing power:
55g Winchester soft point
26.0-26.5g of Win 748 with a federal primer
3050 fps
You usually only had a entrance hole, no exit, massive shock, would punch through shoulders, inexpensive bullet.
This same bullet blew coyotes up in a 22/250, massive expansion.
