If that is what you have to hunt with, then I would look for some of the Nosler 60grain partions, I know black hills loads them and I belive that federal does as well. They shoot pretty good out of that 1:12 twist. Another issue is with that twist the bullet might not stabalize, and really yaw in the deer causeing a massive injury and possible death.
I was going to hunt with my AR15 this year, for deer, because its what I had. I went a head and bought a Marlin 336 in 30-30 Win, great rifle, If you have the little extra money thats what I would look in to, and just buy a peep sight for it, and sight it in.
Anyhow I would look at 60 grain nolser partions, or 55 grain Trophy Bonded Bear Claws, or the Winchester 64grain power points.
Above all as with all rifle calibers, I would take good shots, and have good bullet placement, just be ethical in your shot choices and you should be allright.
Best of luck to you
