terrain, and size and species of deer can make a difference. I like the handiness of leverguns for thick woods where shots are likely to be close.
I Like bolt actions and more powerful cartridges for longer reach if hunting clearings, draws, or open spaces.
I'm a .30 cal fan. I have a marlin 336 in .30-30 that I consider my swampy woods/brush rifle. I've got a Sako in .30-06 that is my "reach out and touch it" rifle.
I also have an old Mauser '95 that was sporterized by my grandfather and belonged to my grandmother. It makes a good general purpose hunting rifle and loaner for friends who want to hunt. It's chambered in 7x57mm Mauser, and has put many a deer on the table (especially if they were stupid enough to eat out of my grandmothers garden in deer season).
