Into the danger zone...
Got a perfectly aligned mold and no cartridges to stick it in. Would these be best with 40-65 or a larger case?

it looks like it might be a little light for good long range performance in a fast twist rifle , in an older slow twist it might work pretty good , kinda depends on what you have in mind for it.

Reckon to try them in the fast twist muzzle loader first, sizing and running through the rifling die. But I sure am pondering a single shot.

that is interesting a 40-65 has a 1-16 twiat so if your rifle is slower than that you might have the real deal.
