I've got a project in the works right now, but trying to narrow down what scope I want. Also thinking about changing things up on my 308 at the same time. I've got 2 of what I consider to be decent scopes. VX 3 3.5-10x40 and Vari-X 4 4.5-14x40. The vx3 has a duplex, and the vari-x 4 has mildot. What are your favorite reticles for 0-800 yards, and for beyond that, assuming a seperate rifle? Also, I've never tried checking into changing reticles. Is this something that Leupold does, or should I look elsewhere? Ideally, I'd like to be able to do rough ranging.
