Although the .243 is one of my favorite calibers, it's not one I'd recommend if you're saving coyote pelts - and CERTAINLY not bobcats - at standard velocities.
If you don't have the luxury of another, lighter caliber, I'd also look to downloading the .243 significantly. If it weren't for 250-yard shots I often encounter with coyotes, my "ideal" pelt rifle would be the .22 Hornet. If you can push a 6mm at similar velocities safely, that'd be where I'd start.
