I am looking for a handgun to hunt deer with next year any sugestions on what cal and ammo to use?

I'd sugget a .41 cal or larger and I'd look at the Ruger blackhawk, but you'd do well at looking for Smith & Wesson and Taurus as well.

If you go with the Ruger single action, add $75 for a trigger job up front.

I would use a Hard Cast LBT Style Bullet. Good luck.
