Trail boss and 44-40

[holsterguy]

Hey guys, getting ready to order from accurate molds. Think I'm gonna get the 43-220C. It's a copy of the original bullet design, but has a crimp groove added.
Being 20 grains heavier than the normal 44-40, I'm having trouble finding a load for it. Want to use trail boss. Any suggestions?

A case full is about 8.5 grains....thats what I use for the lee 240 thats actually 253gr. Seems to shoot to point of aim at 100,so i suspect velocity is around 1200f/sec.With a lighter bullet of around 215gn,I also use 8.5gr,cause I leave the measure full of trailboss.....Just use a casefull,like they say,but no compression.
