Bullet size quandry

[Stephen Borud]

That's interesting Don. I would think part of the reason the paper thickness was different was do to the lack of custom mold makers, or maybe the cost of a custom mold in those days. I know that when a new rifle was bought the buyer would most times buy the bullet mold, and all the reloading utensils recommended buy the gun builder, having different thicknesses of paper would allow the shooter patch to under bore diameter up to let's say groove diameter. I would think the pp bullet would be wrapped to .451 for its final OD. Not having a lot of experience with checking original barrels and chambers I'm guessing. Good stuff though
