just wondering if mixing some flake graphite into a batch of melted bullet lube and then letting it set up and then running it through my sizer would be of any benefit ?
thanks,dennis

Welcome to the forum sealer. Rules are simple, be nice and join in.

I've never tried that, but perhaps some of our cast bullet folks here can chime in and give you an educated answer. Years ago I went to the liquid alox Lee sells and never went back. My lubri-sizer's went in a yard sale.

A number of commercial lubes contain graphite or molybdenum disulfide. These work, and help a little with the highest velocity loads, but add to the soot of the fouling, in my experience. To get to best cast bullet performance, you really want your gun in good cast bullet condition (smooth, constriction-free barrel and correctly sized chamber; firelapping helps a good deal in this regard). If you have that and the right alloy and bullet size, you can even get away with no lube at all for a number of rounds.

well, i tried mixing some flaked graphite into some melted bullet lube, and when it hardened, it had all settled to the bottom. so much for that bright idea.

To add Graphite and get it to stay in suspension you need colloidal Graphite. It is much finer and will suspend. Flake graphite is too coarse and heavy and will separate, as you discovered.

The old Lyman lube contained graphite. The more modern lubes do a much better job than the old ones. That is why Lyman no longer makes the original, or, at least, it is rarely seen.

more trouble then its worth.

In the far away past, I used to tumble my lubed bullets in graphite. This helped a lot in a new gun that had not been broken in yet. It worked fine for a long time but I got tired of the gray smudges on everything I owned!
