Slight taper from leade to muzzle would be good. the other way, not so good.
I see you on the no copper, well unless it's a gas check, for shooting these days.
Geargnasher, Why don't you fire lap that barrel? It isn't difficult at all. Just do it until there is no longer a taper. Your lapper bullets will cut where it is tight and coast over the looser end.
