I get it out of the trap range. I will spend a our or so with a 1/8th spaced screen and sift the top 1nch or so of soil. Last out I got 80lbs. Smelted it down. Its a bit dirty. To remove alot of the non lead items I will dump the shot out in my wheelbarrel and use my shop vac to blow off the dirt and twigs.
I also will walk the out door ranges for 10 min or so and pick up all the non jacketed bullets. Gets me about 6lbs
dont rule out indoor ranges for lead....I mix indoor or unknown lead with my wheel weights I have run about 100lbs of a 50 50 mix and seemed to drop a tad bit larger shot ? Im going to cut it back to 80% WW 20% lead
Sounds like when someone ages, everything moves south, including the lead.
It is indeed possible to have a bullet that is too "Hard". I had some high antimony content linotype that cast a bullet that was almost "frangible" or brittle. If the rifling was not deep and sharp, it would strip the bullet and accuracy would go down the tubes. Had to keep the velocity very low, or cut the metal with pure lead and a little tin.
Too hard bullets can, and I say can not will, increase leading in revolvers particularly if the chamber throats are too large. The bullets, being too hard, will not upset and thus let gas cut by as they enter the throat of the barrel.
I bought several thousand very hard cast 44 Keith bullets and with anything over a moderate load they will lead any of the magnums I shot them in. On the other hand, straight wheelweights from an identical mould, lubed with beeswax/alox2138f do not lead my guns. I also think the waxy blue/red/whatever lubes the commercial casters use are pretty weak at stopping leading.
Sorry about going on about bullets in a shot related thread but if you are having leading problems in a revolver, it could be caused by bullets too hard.
