Okay.... shooting again, since it's Saturday, and the first 24 rings weighed an average of .5333 grains each. Assuming a recovery factor of 80% (my factor for recovering flashing lead (last load was 80.12%
).... gotta be close to true flux loss for dirty lead rings too)
, that gives a useable .4266gr per ring. At 141 grains for the average .454 ball, I need 330 rings, or the recovered rings from 55 full reloads (at 6 per load) to regain one ball.
Not really worth keeping up with, IMHO.
One note: your rings might weigh more if you use store-bought balls. I use pure lead hand cast balls, and pure shrinks a bit from the mold size, so my cast balls measure .4525 instead of .4540 and might not shave as much ring as Speer or Hornady balls with a true .454 diameter. Still..... you gonna need a pretty good sized poke full of rings to get more'n a ball out of it.
