Most are about a 6-8 week wait,
What is your recipe?
I look on streets, curbs loves wheels, also raised medians. any place a trucker lets his trailer jump curbs. I have asked the ranges in-doors and out-doors for lead or who buy/cleans.
Good Luck.
I think if the speed stays below 1200 fps and the bullets are hardcast with 18-22 BHN its ok

I run Hardcast in a .357 mag leaver and pistol around 1150 fps 158gr RN.
If you can find an old sierra reloading manual data for lead.
