I use both,a RRA 20" varminter and a Savage 12FLVSS 26".
While the RRA is a proven 1/2-3/4" shooter,the Savage will out shoot it any day of the week with the same type bullets.
There's a little difference in velocity,but a good bolt action will out shoot an AR almost everytime.
For shooting coyotes,they both will do the job at the ranges you listed,so it's all about what you want.
It will depend on the barrel twist rate,and the bullet that is used. Varmint bullets are usually 60gr or less,and the wind can really push them around at that kind of range.
Heavier Match grade bullets have no problem shooting that far,but I don't use them for hunting,they're designed to punch holes in targets not animals.
