Not sure, but I filled 6 of them about 1/2 to 3/4 the way full and after it cooled off, said it was 20 ounces.
I could probably fit 3 of them (maybe 4) pretty easily in my melting pot at the same time.
But I will say that this lead was a LOT cleaner than the #8 shot I melted down.
Half full and they weigh around 20-ounces would certainly make sense.
The "dirty" #8 shot smelted down was probably giving off slag from (1) powdered graphite which is an anti-stick coating on the lead shot, which ultimately floats to the top, and (2) some ammo makers have sawdust/corncob/plastic granular buffer material mixed into the shot.
It's hard to do, but you can overheat hard magnum shot to the point that the antimony will release from the parent lead and it forms an oatmeal-like slag that floats to the top.
God, I need to re-focus my life......
