Get a rifle that fits you. You will shoot it better. I think most people carry rifles that are too long of pull, and don't know it. The bolt handle should be a comfortable reach with you palm turned up. The handle should land mid-palm.

Get a rifle that suits your hunting style. Do you sit stands/blinds, or do you hunt on your feet?

I still-hunt a lot and shoot deer at close range. I like a fast handling compact rifle like a Browning Micro-Medallion, Remington Model 7, Ruger 77 Ultralight and lever actions like a Marlin 336. I use low-power variable scopes like 1-4x or a peep sight on a lever.

Full-size rifles with higher power scopes are more suited to stand hunting and places where long shots are typical.

The caliber/cartridge is up to you but unless you typically take long shots, magnums are not needed for deer. You would be happy with 243, 260, 6mm, 7-08, 7x57, 308, 270, 30/06, 30/30, 35 Rem, etc. All are good for deer.
