Sold by the ingot~ 5 pound increments.

 Ingots are approximately 8-3/4" x 1" x 2" and weigh 5 pounds (+/- .25). This alloy is comprised of twenty parts of lead and one part of tin (95% lead, 5% tin). The Brinell Hardness Number of 1 to 20 Alloy is approximately 10. 

This has been the standard blackpowder cartridge alloy since the .45-70 Government Cartridge was first loaded in 1873. It is also popular with many of today's Cowboy Action Shooters.

    20:1 Pb/SN Alloy

    Posted by Bud Hyett on Apr 26th 2020

    This shipment continues the tradition of the alloys I and friends have bought. It is clean when fluxed, alloyed as promised and prompt shipment. Although I have scrap lead and tin, thus can make this alloy, I prefer the correct alloy for competition. Reasonably priced also.

    1-20 Alloy Ingot

    Posted by Richard Windsor on Aug 23rd 2019

    Very good and clean alloy. I used to mix my own but lead and tin prices have gone up quit a bit so I buy from Roto metals. Might be slightly more expensive but I don't have to melt down 66lb ingot of lead and search for a cheaper price on tin,

    Best bullet lead ever

    Posted by Paul MANCUSO on Aug 21st 2019

    I have been casting bullets for 58 years and this is the best lead I've ever encountered. Now I only cast for my 73 trapdoor, 405 HBFN, and this 1 to 20 is perfect, no dross! Combined with SPG lube and this lead, perfect bullet, thank you Rotometals

    This review is for all of the ingots in my order regardless of alloy. The only complaint is from my postman !.
