I am fairly new to this forum, and have only recently learned that wheelweights have been pretty much the standard raw material because they have been free and readily available. They are about the most convenient material short of fired bullets from the backstop, and I would use them if I could get them. But they have never been free in South Africa and now they are seldom available as the service stations re-use them.
I knew that there is a move afoot to ban WW in California but you are the first I've seen to say they are not so easy to get. Maybe the time has come to use WW when available but to give some thought to alternatives. Its the same story with linotype. It is hard to find here because the printing industry has long abandoned it. It must be the same in the US.
The answer is to go to first principles and learn how to blend scrap lead from all sources into bullet alloy. Unlike WW, other scrap often comes in large pieces. My experience of several years of commercial casting is that scrap on the average can be expected to contain 1% antimony. You melt it in a big melter like a fish fryer and add another 5% antimony and get yourself a big quantity of ingots for casting.
The antimony must be bought new from a local foundry or from the Antimony Man. In my part of the world it is about $6.50 per pound. I think WW are too soft even for handgun bullets but if you have found them OK as many do, then add 3 or 4% antimony to the scrap. That will give you WW alloy. Don't rely on such things as linotype.
Forget Lyman #2 alloy. It contains 5% tin 5% antimony. It is thus expensive and no harder than the industry standard 2/6 alloy. Tin is very expensive and does little for hardness. Its purpose is castability but the antimony provides enough castability on its own. So dispense with the tin and just add antimony as described above. By adjusting the antimony percentage you can blend any alloy you want including rifle bullets any time you want.
