A lot of Rotometals' prices include "free shipping", so that figures into the pricing scale as well.
I last bought Linotype about 5 years ago from a young man and his Dad to help him finance books and tuition at U.C. Irvine. I gave $2.00/lb. for what turned out to be REALLY GOOD Linotype metal, 200# was all he had left, and I snagged all of it. I still have about 150# of that left. Does that stuff ever cast nice bullets! Harder than woodpecker lips, and harder than needed for bullets, but it casts BEAUTIFULLY.
My most-used alloy for the past 20 years+ has been half Lino/half lead, AKA 92/6/2, Taracorp, or Hardball alloy. One thing that Linotype casting taught me (and Lyman #2 alloy casting reinforced)--Loverin bullet designs THRIVE upon the added tin in Lino or #2 alloys. Now when I cast Loverin designs with the 92/6/2 "default" alloy, I add 2% pure tin from Rotometals to sweeten the melt and enhance fill-out of those little tiny drive bands.
