Since that is a very common load, I bet your BDC reticle has aiming points set up for it already.

I took a buck at 140 yards with 90gr BH209 and 260gr Harvester Scorpion and there was very little drop from the 100-yard zero. Granted, 140 isn't 200, and I think 90 BH209 is a little faster than 2 Pyrodex pellets, but I'm sure the BDC will be on target for you.
