6-7 grains of Universal (a good substitute for Unique) and bullets
from the 200 gr Gold Dot HP to a 240 cast Keith work well in my Bulldog and 624's.
Hornady lists 6-8 gr Universal for both their jacketed and lead
180 gr. bullets. Start with 6 and work up in .5 gr increments.
I have a Crimson Trace grip on the Bulldog and it seems to tame
the recoil and is more accurate & faster than the fixed sights it comes with.
I also shoot a lot of 44 Magnum so that probably helps me control the light Special.
