The 55's have more of a blunt/tangent style frontal section, and don't have near the jump to the lands.
I tried pretty hard to get the 62's and the 70's to shoot, with no luck. It is important to note that this effort was in NATO chambered AR's that are very different than a 223 REM chamber.
The 55's are not finicky to tune at all.
I also fooled with the 55 grain Nosler E-Tips. No luck getting them to shoot in NATO chambers either. They do however, shoot great out of my short throated Wylde chamber with Benchmark powder.
If it where me, i would not choose the 62's or heavier for Coyotes. They are tough bullets, that will leave the barrel with a slower velocity.
(this is all theory though, as i have never taken a Coyote with either)
I use Sierra HPBT #1390, Hornady 55gr and 60gr Vmax and 55 grain Nosler Ballistic Tips for Coyotes.
Interesting, thanks. It's possible that I would also be shooting them at some point, from a 16" and 20" NATO chambered barrel.
