The Speer 200 grain SWC-JHP "was" one of my favorite .41 bullets...unfortunately a few years ago Speer stopped making that whole line of bullets.
8.0 grains of Unique will run that bullet about 1025 fps from the 6" barrel as they run 950+- out of a 4". From a 4" barrel 9.0 runs 1100 and 10.0 1180 with bullets from 200-220 grains. I use those loads almost exclusively in my Smiths saving the really heavy loads for my Rugers and Freedom Arms single actions.
Here is the link to a commercial caster whose favorite caliber is .41...he has a bunch of HP and solid bullets for .41 at very good prices...
