RE: Gettin my first deer rifle.
You have a fun delima on your hands right now and I' m sure you will get a lot of enjoyment out of your new rifle no matter what chambering you choose, I would offer this advice though. I know its boring as heck and not new or glamorous at all, but the 3006 is still the most versatile cartridge thats commonly available in factory offerings. If you ever plan on getting into reloading you will be able to come up with alot more different types of loads easier than with any other cartridge. Ammunition is cheap and easy to find too. Have fun deciding on your new gun.
