Ash - the paper patched bullets did not reduce fouling, but due to deformation, slugged up to fill varying groove diameters common in those days. A grooved lubricated bullet needs to be closer to groove diameter to shoot well - not so the paper patched bullets with base wads.
Anyone know if when the BP grease groove bullets came on the scene if they kept them at bore diameter as they had in the paper patched bullets?
Is there a reason that a soft GG bullet wouldn't bump up like a patched bullet does?
I suspect that a long bullet of bore diameter only bumps up in the rear third or so of its length leaving the leading half or more bore riding.
A high speed film of a bullet shedding its paper patch and a look at the rifling on the bullet would sure be nice to see!
