re: Thoughts during Finals Study Break- Building a Sniper Rifle

RATW,
500-800 yards is a LONG way off. I don't have anywhere to shoot that's even close to that distance. I think there's still a range south of S'port that has the only civilian 1000 yard range in LA.

Before jumping into such a specialized area of shooting, you might try shooting your 270 at longer distances. How far away are you shooting now?

Long range shooting is a special subculture of it's own utilizing special scope bases, high end optics and very accurate rifles that have been worked over by a gunsmith.

Yeah, your 270 Win action can be rechambered/rebarreled to a nearly limitless number of different chambers, depending on just what it is you want. Be prepared to spend a LOT of $$$. Personally, I wouldn't change a 270 Win rifle into a 308 Win for the type of shooting you're talking about. I'd keep the 270 in case I wanted to resume hunting someday and start afresh w/ a build for a long range rifle.

You can find lots of info at some long range shooting forums on the 'net.
