There seems to be a ton of calibers for the Contender, especially when you add in the Wildcat calibers.
What would you use or have used, that you'd call the best wildcat caliber for whitetail deer at 200yds or less?
What about the best caliber for coyotes, feral cats, bobcat and fox out to 200yds?

Right now, I use 7mm-08 for everything, including the above varmints, plus hogs and deer on the Encore platform. Only because I never know what will pass by.
I have a Marlin .17 HMR that I shoot stripper necks from the ponds and an occasional beaver.
I've already got 5 G1 Contenders, (4 pistols and 1 rifle) and pistol barrels in .45c and 30-30.
I'd like to explore the other calibers, like a .17 fireball or .221 Rem. and maybe the 35 Whelen.
But I'd like to get your input on your choice, before I start collecting different caliber barrels (you know that's addictive)
and still may not get what I was "looking/hoping" for.
Thanks
