I am going to second the .308 Winchester. I have used 150 grain and 168 grain out of a 700 the bambi don’t wiggle after getting smacked with either of those. 150 grain hand loads can cover a lot of short range (here in TX 150 or there about yards and the 168 and heavier cover longer range (150 meter and up).
The 700s I have shot 308 and 6.5x55 are sub MOA in my experience. If you do your part the bullet gets the job done.
expect to drop a kilobuck by the time your mount optics on the rifle.
I own a 1896 Swedish Mauser, (6.5 x 55). The bullets offered in that caliber have some of the very best ballistic coefficients available, and they are super accurate. I like the rifle also, peep sight rear and hooded aperture on the front on mine.
