hahahhahhah, I will definitely put some voodoo on your deer and they'll just fall over dead - no need for arrows.
In all seriousness, momentum is not the cause of penetration/bone breaking. It's a deep rabbit hole to go down, and I don't recommend doing it if you're casually interested.
Single bevel (i'm not familiar with your particular head, but the mechanical advantage of the blade matters too) will outperform double bevel and three blade broadheads in regards to penetration/bone breaking.
There isn't much reason to shoot at a deer's leg bone when they're broadside. Most people think that leg bone goes straight down - it angles forward a fair amount, well in front of the majority of the heart/lungs. Obviously you can hit there because the deer moves, or because it's quartering to. Honestly with that draw weight/length, you're probably looking at needing a much heavier arrow to break through that bone. And to do that you'll be giving up a lot of trajectory - meaning your effective range is going to be much shorter than you probably would like it to be.
I'd be shortening my effective range to 20-25 yards, and shooting a 650+grain arrow, or stick with what you have, and don't take quartering to shots, and aim 4-5" behind that leg bone, and live with the results.
