so I came up on a vortex diamondback 4x12-40 with the deadhold bdc reticle. looks pretty sweet and its brand new!! I was thinking of putting it on my 300win mag, but before I do, I want to know what u guys think of this scope? any feedback will help, I have read relly good things about em. I di not buy this scope, it was a trade that I think I got the better half of the trade.
