I use conicals for the simple reason there is no real need to lube over the cylinder, the long contact area is good protection against chainfire.
I prelube with liquid Alox so I dont have to carry messy stuff to the range (sods law says you will have a mishap and get it every where)
Pure lead ones press in a treat in my Rogers and Spencer .44, but as you say accuracy ain't too good.
Try thick wads to buffer the bang, 777 is more violent than BP.
....
A ball would be a lot lighter than a conical, and if you look up reloading charts for cartridges, as you increase the weight of the projectile you reduce the powder charge. It's mostly to reduce breech pressure.
Life would be so much easier if there was a weight chart for 777 it gets awkward working between weighed and volumetric measures. For BP guns we are supposed to use measurements by volume Pyrodex works out like for like.
777 is 15% hotter so Hodgdons say reduce your charge bt 15% by volume.
We use volume at the range because the spout of our powder flasks will deliver the same ammount whether it be BP or Pyro. Not so forr 777 you either have to use a different spout or go over to vials/phials and pre measure.
Pre measure has major benefits, its safer to pour that small ammount than have the equivilent of a bomb in your hand, it also means you can get your charges more accurate by weighing on precision scales.
Can some of you weigh 10gr by vol 777 and tell us what it weighs to create a standard measure to calculate a scale from. perhaps other measures like 20gr and 30gr.
The best I can offer is 17.5gr by vol in my measure weighs 11.5gr
