Jeremiah welcome if this is your 1st high power rifle think about looking at someone elses name on your rifle, I had a pre 64 M70 /270 once that had that very same thing I liked the rifle, but with the name on it it had to go.
Both calibers you are looking at will do and have done a very respectable job on game for years.
A couple things to consider long action vs medium action. The cost of ammo is somthing to consider, if you don't reload,. There is a lot of 308 ammo on the market at a good price, where as the 270 will probably be more expensive. I would guess that if it's your 1st high power rifle your gona want to shot it as much and as often as you can so ammo price is a factor.
I am sure no matter what you decide to do will be the best for you. All of us who responed to your tread all wish you the best and welcome to the brotherhood of shooting and hunting
