Et, those pics look like you've got some corrosion going in those cases. Rough dirty inside case necks crap up accuracy.
If you regulate the front sight so that with the ladder folded down to be dead on at 100, ranging shots not particularly needed. The markings on the ladder will be very close.
Here's the copy of an original Sharps bullet I shoot. It measures .435 as cast, I wrap it with 20lb all cotton paper to 451. Haven't got anything for accuracy I'ld take to a longrange match but it'll hold 6inch at 300. And knocks elk dead.

the most expensive bullet there is isn't worth a plug nickel if it don't go where its supposed to.
