I have both. I have had the Win. since 1970. I planned on making it into a .300 Wea/. but at the time, Douglas barrel company did not freebore. So when I deducted the difference, they were both about the same velocity wise. I stuck with the Win. I was in an area where Douglas was the barrel so that is why I didn't consider others.. Today, I guess I would still go with the Win. In a 700 action, you can seat the bullet out as a Win.'s throat wears and keep the bullet close to the rifling. A 300 Wea. just fits in the magazine, and there is no room to seat it out farther.
