Fast twist .223. It can do it all economically.
I'd say this is the right answer....
There is something to fast twisting and terminal performance.....
In your shoes, I'd run a .223 with a 7" or 8" twist and shoot the 55-60 grain Vmax. Killed trailer fulls of stuff with these bullets from an 18" 7" at 3100 MV.
What those bullets do, with that twist has to be seen to be believed on big coyotes or either similar stuff. Electrocution. Other less frangible bullets isn't quite as dramatic but still effective.
If ranges were longer, I'd have different recommendations ..
