RE: Hunting pistol
Depends upon what you want to hunt with it and how much cost of ammo is a concern.
I have a 44 mag taurus (raging bull) which I use for deer hunting and have carried with me elk hunting (close shot only). The ammo is significantly cheaper than the others which is one reason I went with a 44. It has two deer under its belt and has worked well for me. It was a little rough when I got it but with a little wear is very smooth now. I use 240 gr for deer. Buying some hornady xtp's 300 gr for elk this nov in case I get lucky enough to have a close shot.
Eventually, I plan on buying another revolver not sure which caliber. Planning on a freedom arms or ruger redhawk.
I highly recommend buying a non-ported revolver. My ported raging bull is very nasty on the ears and I will never buy another ported firearm period. I have slight hearing loss already so am pretty conscious of this now.
Have fun.
