A worn-out SCUBA-diver's weight belt

found its way into my reloading shed a couple of months back, courtesy of an acquaintance who had such a great time [along with his son] at a recent guest day, and donated it to me as a thank-you. And before anybody takes to task about how a weight-belt filled with lead shot can wear out, it appears that constant immersion in salt water over a period of years play gip with the stitching.

Anyhow, half an hour work with mrs tac's unpicking device and I was the proud owner of about 45 pounds of mixed-grade/size lead shot. Melting it down resulted in some pretty gruesome and plentiful dross, but once that was skimmed off, what beautiful shiny lead was there for the casting!

The bullets - 535gr Miniés for my Musketoon and 450gr FNL .45-70 Govt for my Winchester High Wall - came out sharply filling the moulds and of very uniform shininess. Even chilling the 405s straight from the mould into a pail of water didn't change the colour, just seemed to make them very smooth and professional-looking.

My experience has pointed me at any dive shop where old gear might be found - in particular weight-belts with shot, rather than the clip-on lumps of lead one often sees.

Dive weight shot has a potential of not being pure lead. I have found in recent years that a lot of dive shot is also made from wheel weights and other lead alloys as well. I have seen shot that has been made from pure zinc as well. Be aware of dive weight belt ingots made in the last decade or so as they may have been cast from wheel weights which may have also included zinc. For your Minies you want pure lead and for your 45-70 lead alloy will do. My suggestion on the shot is cast a sample and test either with your nail or a BNH tester.
 
Lead shot comes in several grades, dig around the web and you will find the various descriptors (hard, chilled, etc.) that signify the addition of various hardening agents.

Suggest hardness testing the stuff you got. You probably need dead soft Pure lead.

FWIW, the only attribute needed in a dive belt is actually that it be heavy. It makes a great way to dispose of contaminated or questionable lead, casting weight belt weights.

I have sold a lot of salvaged shot to guys that were sewing it into weight belts too.

Thanks for your input, Gemtlemen. Due to the total absence of wheel-weights here in Yoorup this here stuff seems to be eminently suitable as it comes for the .45-70 bullets - I don't shoot them fast enough to need a gas-check but they are still tooling along at just over 1400 fps. You are all right about the Miniés - too hard - so I tossed them all back in the pot.

Best to all here.

The lead shot in bags is relatively recent for weight belt use. They first came onto the market something like 25 years ago. Before that it was either cast lumps of naked lead or solid lead dipped in plastic.

The old cast lumps that threaded onto the belt can be dead soft or slightly harder. I know because I've been cutting up, melting and casting with my 40 year old weights over the past year. Using the artist's pencil method for estimating the hardness I found that about 3/4's of the lead I've got is suitable for round ball and Minie. The rest will be used for my upcoming bullet casting for my .38-55 loading.

So if you find any of the old bare lead slip through weights it's very likely that they'll be great for casting. The first time melting them there is a whack of dross from all the corrosion and salt on the outside. But the lead inside is nice enough.

no wheel weights how do you balance you're wheel/tire combos
 
If you can put a big enough order together there are places that will sell re-refined 99.8% pure lead for $1.30/lb in 60lb ingots. Shipping 600 lbs from Vancouver to Camrose AB cost me $200.
