I've got that same scope on a .243 that I take yote hunting pretty regular. IMO, that's the best scope for the money. I beat the crap out of that rifle on the 4 wheeler and the zero holds steady.
Anyway, the Leupold web site isn't very specific as to what the hold over points are for the LR duplex. I think they are the same as the B&C reticle but I'm not sure.
What I did is get my ballistic info together and call the custom shop. They ran my ballsitics through their computer program (which came out almost identical to my program, but its nice to have the expensive software back up your numbers). Turns out my load was a great fit with the over-the-counter reticle so I just bought the standard scope without using the custom shop. I'm biased, but every time I buy something other than a Leupold I regret it.
