So I know very very little about rifles. But I've always wanted something that will shoot a thousand yards just to say that I have something and be a bit of a challenge. I purchased this rifle yesterday after doing lots of research and figure that this is what I wanted. It has the vortex diamondback tactical 4-12x40 on it already. Curious if you guys have a similar setup and how far are y'all shooting out and what ammo are y'all using?
