Over here,ww is getting really scarce.Last year,I went through a 135#(5 gal pail)to sort out only 43# of lead WW.Not worth the effort.
I use range scrap and mix(for 9mm)1/2 1/2 range scrap and either WW when I have some or2/3 1/3 rs+linotype of which I still have a couple hundred pounds.Drop in a cold water pail and you get a bullet that's hard enough for velocities over what you can get in a 9mm.
