GeorgiaHunter is a great psychologist!
You can shoot a deer with anything, and eventually it will fall down. Only question is when and where?
If you want it to drop in its tracks, then you need to go with a .270 at least.
And note that a .308 and a .30-30 are both lighter guns than a .270. You need to look at the powder charge, not just the bullet calibre.
Guns that would drop a deer in its tracks include the .270, the 7mm mag, the .30-06, and any of the bigger magnums.
With a .308 or .30-30 or .243 or anything lighter you are going to be searching for your deer, so you better get good at following blood trails, and carry some long rope with you in the jeep in case it barrels into a ravine.
Personally for New England I would not recommend my own gun. It is designed for deer AND elk. And no elk up there.
