These graphite cores were not originally designed for this test, as I mentioned above.

Nov 2, 2023 · I use a method given in Handloader # 50 by Rick Jamison page 18. It uses bullet weight and it works verry well. You have to use a little math and cast a few bullets and use his chart. I use a 405 grain 45-70 bullet but any heavy mold will work. It will even tell you what alloy you have. I have saved myself a lot of trouble with mystery lead.

On pure lead, the reading must be taken very quickly. ** WW (wheel wts) vary in composition and your results may vary slightly.

Nov 15, 2007 · A guy on cast boolits asked about moving sights and asked for a chart. He got a lot of arithmetic and jokes about arithmetic and a couple of mnemonic aids, that I always forget. I made a 1 page chart, it's in .doc and .xls-needs some cleanup and correction. That came out well. I'll attach the files. Help!! Thanks; joe b.

After an hour of trying to take readings on a variety of lead alloys I was very frustrated.
