270 is an excellent choice and I agree with bigbulls on the grain choice for deer stick with 130. I have taken many deer with a 270/130 grain bullet and it has always performed very well. I personally prefer 130 Nosler Ballistic tips or Hornady ammo offerings but that is what I found provide me with the best accuracy & field performance for my situation. I have also taken moose and elk with a 270 using the 140 gr failsafe and 150 gr nosler partition, however if you ever tackle these critters with a 270 then make sure to know the limitations.

Win mod 70 is a good choice. I prefer a detachable mag to a blind or floor plate hinge but again that is my preference. My current 270 is a browning abolt SS stalker and it shoots excellent. I also owned a Rem. 7600 and Rem 700 bdl in a 270 both were solid hunting rifles.
