Don't know if the Burris BD w/side focus will have more elevation than previous A/O models, but I doubt it. There's just no comparison in that regard vs. the Leupold 'LR' series. With the Leupold 6.5-20 or 8.5-25, you get 72 moa of up. Compare that to the BD w/39 moa. Both have 30mm main tubes, so the BD must do something different inside, or maybe Burris just doesn't get that we long range guys need UP.
OTOH, the BD is plenty of scope for long range shooting if you have a flat caliber, or use tapered bases/rings, or maybe best of all both. I watched a good friend compete very successfully at the NBRSA 1,000y Nationals in 2002 w/a Burris BD in 8-32, atop a tapered base. His was the only Burris scope on the line. All others were NF, Leupold, and a Tasco and a Mitchell (external adjustment). My pal had to remove his NF because his rig was over the 17 lb cutoff. The NF weighed 36 ounces vs. the 27 of the Burris BD.
Another mark maybe in favor of the Leupold. Their LR series weigh about 20 ounces.
Last consideration: if you still want to try a Burris BD, but will settle for one with slightly different cosmetics (and a lower price tag), check out the Pentax LS-30, as in Lightseeker w/30mm tube. Made by Burris to so-called Pentax specs, but the only differences I can see are the Pentax bell is significantly longer/more gradually sloped than the Burris version, and the Pentax has a conventional mag ring feature, vs. the annoying Burris magnification feature in which the entire ocular lens assembly rotates. (If you got a flip-up cap on it, you gotta keep it closed...)
Dealer price on the Leupold 8.5-25 is about $693.00 w/plex reticle, vs. $592 for Burris BD, vs. $485.00 (through Freedom Armory in PA) for the Pentax LS-30. F/A was about the only place I could find that had the Pentax for anything below 'retail', and it was WAY below, so maybe worth a roll of your dice?
Final comment: the NightForce Varminter (A/O style, no side focus) scopes were UP deficient too. Got a 12-42x56 w/30mm tube (like all NF scopes I think) which has a measley 40 moa. Their NXS line w/side focus features quite a bit more UP, at a price boost.
