Original paper patched bullet designs?

[Don McDowell]

Jim, sharps always referred to the patched bullets as naked, and the greasers as grooved.
In their last catalog they were still offering 50 cal components, the 2 1/2 case was offered loaded with either the 1 1/16 bullet with 100 gr. of powder or the 335 gr express grooved bullet with 110 grains. Their only listing for the 1 3/4 case was with the 1 inch naked bullet (425 gr.) with 70 grains of powder.

I sent an order off to Brooks for a dual diameter 40 bullet that is similar to yours, hope the mail lady brings it soon so the experimenting can commence.
