I think I'm gong to have to call this a wash. With my 500 gr bullets there is no way I can load them without damage to the bullet. Well not with 70 gr or even 60 gr of black powder. I might be able to do it with 50 gr but that would probably be a squib load.
When the powder is dropped down the tube it fills the case to within .3" of the case mouth. In order to achieve my max. allowable length to chamber in my Sharps I have to seat the bullet .5". Additionally I have a .060" veggie wad between the powder and bullet so I'm compressing the powder over 3/8". I didn't even check if I swelled the case by seeing if it will chamber. The ring in the ogive of the bullet is pretty sufficient and would probably affect accuracy.
