That is not totally true... most loads are grain for grain with t7 until you get the the heavy bullets 300 and greater. Since BH is progressive it takes more BH to shoot the light weight bullets than it does T7. And when you do shoot laods of T7 and BH - with the heavier bullet you will get 150/200 fps more speed with the BH... The advantage is that you can load larger loads than t7 and increase the velocity without increasing pressure at any given time in your bore.
Look at this chart and you will see what I mean....
Bottles are smaller but also use LESS grains of powder so it pans out

I believe that they all have a place, the traditional rifles will work best with black or pyrodex, the plunger type inlines that use #11 or musket caps work well with pyrodex, the sealed action 209 primer rifles should work with all powders if the design is good but can excel with Blackhorn if loaded right. Blackhorn is a progressive burning powder and works best at certain pressure levels, these are easy to reach with the heavier bullets but require a tight sabot and certain minimum of powder with light bullets.[ my personal opinion after burning a couple of cases]
what sabot's do you suggest with the BH209?
