I'm loading 218gr cast bullets into shortened .41mag cases and am at a loss for black powder data to use. I'm aiming for around 660fps. Does anyone happen to have any data for this cartridge?
 
Cartridges of the World says 200gr cast/5.5gr Unique /765fps As advised work your way up don't start at the top.

Don't increase the charge initially to 'counter a heavier bullet '
Start lighter and see how it feels if you have no access to a chronograph. S & W break tops are not as robust as a solid frame...don't want to see any trainwreck pictures.
And stay away from Bullseye...it's not as easy to meter safely IMO. Personal thoughts only
