This is not your typical 2 ring Prussion bullet. For your consideration one McKee & Mason 285 (type) Prussion bullet. You will find this bullet to be in very good to excellent dug condition. The patina is a striated white to light white to grey to light grey colors...typical of a salvaged lead bullet? And yes I do not see a single patina chip. Both rings are fairly light.  The top groove is the most shallow shallow. The cavity is ogival. Measures about 0.665 x 1.145 inches. The general thinking on most-2 ring basic-Prussions is this bullet type is Machine pressed & turned...per Thomas. I think these wood mold Prussions fall somewhere outside of a basic 2 ring Prussion. I don't remember seeing any info out there to read on this particular bullet. Best of all dug from the Corinth - Shiloh area.
