So I have an XLR chassis on the way for my T/C Venture .308 and want to upgrade my glass. I have made a couple posts on the bolt gun thread about this and have e-mailed T/C and it appears that nobody makes a one piece 20 moa mount for this gun. That said, I currently have a Vortex 6-24 2nd gen Crossfire and want to upgrade to something that will let me reach out to 800+ yds. with my current two piece mounts. Holdover is not a problem as I am used to doing it. Any suggestions for a scope that has good elevation adjustment and maybe a BDC reticle to help with holdover in say the $750 price range?
