I should have said that I am a lefty and I can't get any of those 3 calibers in a standard gun, hence, buying a .223 and having it rebarreled. I personally think the .223 is too much for fox fur and want to go with one of the three calibers listed. I plan on keeping the bullet gr. weight low to avoid fur damage as well but having quick humane kills is always top priority. I know there is a gun and bullet weight that will do both. I am leaning toward the Mach II and the Fireball only because they are a tad different. I figure if I have a semi-custom gun, I should have a semi-custom caliber. LOL!! I will go with the 17 though if I like it and feel it will do the job. Just want to hear some opinions.

Thanks pharaoh2!! Good advice.
