Good score on the divers weights Mike. Gotta avoid the wheel weights that some use, they contain too much antimony that makes them too hard to swage into the rifling properly. I got a bucket full of fishing sinkers I pick up when I can find 'em.

even adding a bit of tin for mold fill (a common practice) will have those minnies smaking the paper sideways if they're thick base as intended for that gun. It was considered the "magnum" of the day. Are you going to size em round to land dia, if I recall is 575?

From what I've read there is no need to size them...Parker Hale recommends (owners manual) the Lyman 575-213 mould and this provides the right skirt/cup for this barrel (.577)
I've watched some video's on You tube and the accuracy of these guns, using these Minies, is pretty impressive.

They are very accurate

What is the hardness on those belts? That is somewhere I never thought to look for lead.

Oh they're dead pure. I dove enough and shot c&b enough to have a handle on that. Usually if you can sing a thumbnail it's pure

I found if I sized mine if only for the purpose of uniforming my accuracy climbed

The design of these Minie's really negates the need to size your bullet as the cup is very deep and the lead 'skirt' is soft enough to flare out into the groves on ignition.
This is a pic of the cup and a .45 cal ball....you can see how low into the cup the ball sits, the cup captures the blast and forces the side walls out.

Oh I get how a minie works. That's not a thick enough skirt for the loads that gun was meant to take. If you're mild loading that tank your fine with the thin skirt. If it's being loaded as intended you'll flare that skirt upon muzzle exit and accuracy will crash. You got to take a bit of a shove to do many of what's in this pic but it is the intended. I know I sound like justin with the word "robust" but, for light (not what that gun was intended for) loads you may do OKAY. Fire as intended and your thin skirt combined with a grease grove hinge point so close to bottom will flare it. Think of it this way Mike. You said the base design is to flare to fit bore, right? well don't think that paper skirt will immediately stop flaring as gases escape muzzle
