@Toby Bradshaw I was trying to say that the same weight 22 caliber bullet pushed at the same velocity would be flatter than the 6mm.
Agreed!
Admittedly I didn’t put much thought into the what it would take to reach the velocity.
It was my understanding that @urbanrifleman was making the comparison between the 6 Creedmoor and 22 Creedmoor, so I responded accordingly -- 6mm vs. .22 with the same case capacity and bullet weight.
For a coyote rifle it matters a great deal whether you plan to save the fur. I do keep the pelts, so I use a light, fragile bullet to minimize exit holes, even though wind deflection and penetration through bone suffer as a result. Light recoil is a plus, though, since I have a "carrying weight" coyote rifle.
If my priority was simply to kill coyotes in the places I typically hunt I'd be shooting a 55gr-70gr bullet at 3800-4200 ft/sec, which is prime territory for a 6mm of some flavor.
On those occasions where I have a chance to shoot coyotes at longer ranges, with the time to use a rangefinder, I employ a 6BR with 95gr Berger VLDs. Once I am into ranges that require turret-turning or holding over, absolute accuracy and wind deflection are more important to me than MPBR.
YMMV.
