After I tried Trail Boss and liked it I purchsed the 4 or 5 lb container at ca $14/lb. I prefer Trail Boss for all my lead and plated bullet loads in the older black powder cartridges - 38 Special, 44 Special, 45 Colt, 38-40, 44-40 and even 45 ACP revolver loads. Trail Boss meters well, no possibility of a double charge in those tall cases, excellent accuracy and milder perceived recoil for the same velocity.
