In your opinion......what is the best sniper rifle out there and why.
.50 BMG Barret rifles.
At ranges where .308s and .338s start to peter out, the .50s still have a lot of real estate that they can cover.
The best BCs you can get with .308 bullets is around .500, while .50 bullets can have BCs over 1.0, meaning they buck the wind much better, and are slowed down far less by air drag.
