I have nothing against Taurus, my best friend shoots one, but by the same token, i would have spent the same amount of $$ and went American with a single action Ruger, but that was his personal choice. Side by side his Taurus and my Ruger shoot the same to 75 yards, after that the porting really starts to mess with our cast bullets. I also don't care for the kicked in the chest feeling that i get from the ports everytime i pull the trigger.
I like cast bullets for hunting either my namesake Keith 429421, or a WFN bullet, I am currently hunting with a 250 Keith over 9.5 gr's of Unique for just over 1000fps and it will shoot the length of any deer.
For factory ammo i like the Winchester White Box 240gr soft points, the insure penetration and a good hole in, good hole out. A .44 bullet doesn't need to expand if it has a good nose profile (but those JSP's WILL expand). We gave up on the XTP's a long time ago, after several failures on game, as well as the high cost. I am a fan of heavier going slower, rather than light going fast in handguns, that is the one way to be sure of performance in a handgun.
The iron sights will serve you well, if you don't intend to shoot much past 75 yards a red dot can be your best friend on a hunting handgun! Good luck to you, one you get the hangun hunting bug it's hard to lose!
