Anyway these are heavy for cal high sd options beat suited for penetration and increasing hit probability at distance due to high bc and sd. Neither of which you need for coyotes and gophers. There are better attributes out there for that. A .243 would make my list for that as only 6mm and run light for cal. A .22-250 makes even more sense than that and maybe a .223 or .204 if you had to have and extra short AR length action platform. The .22 arc is same thing, heavy for cal deep penetrating high sd options that suit big game much better than gophers and coyotes
All three are the wrong formula for coyotes and gophers...speed with low sd and light for cal is what you want there. Not slow high sd heavy for cal.
6 ARC bolt gun data from Hornady shows 5 powders that will push a 58gr Vmax at 3550-3600 fps. That'll provide a +/- 2" MPBR out to 283 yards (223 55gr @ 3250 fps is 260 yards, 204 Ruger 40gr @ 3750 fps is 299 yards, and 22-250 55gr @ 3650 fps is 289 yards) so the 6 ARC is right amonst the top handgul of traditional coyote cartridges for point and shoot effectiveness at typical calling distances. Even the 6 ARC loaded with the 80gr ELD-VT @ 3050 fps has a respectable MPBR of 260 yards. 80gr ELD VT impact speed at 300 yards is 2420 fps, 22-250 55 Vmax is 2550 fps, so it has plenty of retained speed to make splats. (500y 1950 fps 22-250 55vmax / 2050 fps 6 ARC 80 ELDVT) I'd say a hunter would benefit more from the 25% less wind deflection with the 6 ARC 80gr than he would the 11% further MPBR of the 22-250. If you're long bombing gophers, the wind deflection is even a bigger deal

Found my own answer, 1.9 gr of h2o capacity, and a 40 degree vs 30 degree shoulder. - dan
6 ARC is 30 degree, what I find online for the PPC is 30 degree also
ARC holds about 34 grains water
