I have this in a DC mould and I know this is a huge longshot but I'm looking for the zinc washers this design requires. This was a Harvey design that cast a zinc washer around the mid-section of the boolit as a type of scraper to prevent leading build up. This wasn't a gas check, it was hollow in the center, I'm sure somewhee there are thousands of these laying around and noone know what in the heck they were used for!

Are you sure you're looking at a 358477? I have that one, and it is a plain-base semi-wadcutter. Definitely not one of Jim Harvey's designs using the zinc washers.

The Lyman Moulds that take the zinc washer on their base are #358500 - a 149 gr. SWC with smooth sides , no lube groove(s) and #358502 - a 119 gr. SWC with a rounded nose (almost looks like a semi-auto boolt) and #358503 - a 125 gr wadcutter with a small bump / point on the nose (but not the standaed button nose) and it has 3 grooves - all three look like crimp grooves.

#358477 is a 150 gr. SWC , plain base , in the Keith style ... it has no provisions for zinc washers it is just a plain boolit with crimp groove and a wide lube groove like Elmer preferred .

Show some photo's of whatcha got !

358477 is my accuracy bullet in 38 special. If a gun won't shoot with that and Unique, it won't shoot at all.
