K22 said:Rifle - Tikka T3 Lite or Browning X Bolt Stalker - I have both and they are outstanding rifles - accurate, and excellent handling in the field.
Caliber - if you leave out wolves and mountain lions - 223, with those critter added - 243.
You don't need a wildcat - these two old standbys will do the job quite well.
K22 & I are on the same wave length....since you added the elusive & tempermental predators ....243 Win with 85gr or 100 gr Sierra. For coyotes and smaller....223 Rem with 55gr Sierra.
