This is my first post on this website. I'm a high school senior in Texas. I have been hunting all my life, and am wanting to get into truly long range shooting. I've used the equipment i have to take game out to 430ish yards, and targets to 600. My main rifle is a Winchester model 70 .270 made in 1965. Its in a Hogue overmold stock with the aluminum block. My question is, should i use this rifle, or a Savage model 10 factory rifle in .270 as a starting point for a long range rifle? The m70 shoots sub MOA easily, and I havent tried grouping the savage. The savage also has a much thinner barrel than the winchester. Are either of these suitable for LR use?
