I had my NE .223 rifle for years, 1:9 twist, 22" bbl single shot.. just a few weeks ago, loaded up some berger 70 Grain VLD's with a .370 BC est around 2800 fps with 24 grains of H4895, max load was up to 26 grains but gun was hard to open in 95 deg weather, should buck the wind very good.
Don't let anyone tell you a .223 will not kill coyotes. just a few posts up some guy's dad killed a coyote at over 500 yards with a wimpy .22 mag
Those guys swear by this weakling .22 mag, killing power on coyotes, and a ,223 is like a .30-378 Weatherby magnum IMP., compared to a .22 mag being a .30 US carbine .
The reason .223 is not as effective in the military is because of the enemy hyped up on PCP sometimes, and the FMJ ammio does not expand, if the Army used Ballistic tips in the ,223 they would be way more deadly, but Geneva international laws prohibit the uses of them.
a 30 lb coyote is not the same as a 150-200 lb man either
the .223 is plenty, and with those heavy pills will go way out and drop those dogs.,
let us know how they shoot.
22-250 will have more fps velocity, but under 300 yards no coyote is going to tell a difference, and 90% of 22-250 have the 14 twist, so a 1:9 223 wil stailize the heavy bullets better for long range power and wind bucking.
