It was the uranium that it used to be that spoiled.. The lead is just the remnants.Cabela's had a clearance on pellets 2 years ago $3.50 a tin. I bought all they had on the shelf. maybe 30 tins.
it's not like they are going to spoil with age
Pretty crazy to think that all lead was once uranium then depleted uranium and finally to lead once its fully decayed.
Thank god its not that abundant now or we would have NEVER made it this far. Lol.
There a good pbs doc on it called "uranium twisting the dragons tail".
