Has anyone used the old 44/40 Lyman #427098 bullet in an Open Top? I ran out of my cast up stock of RCBS 200gr. and I have a large supply of the #427098, so I loaded up some sized .428dia. lubed with SPG. and 3.7gr. of Trail Boss, and crimped in the top grease groove. They shot very good, and no sign of any leading.
