Hello, Incitatus..and a big welcome to the facinating...and addicting world of hand-loading! The use of pure lead is not to be recomended except for muzzle-loaders and percussion revolvers..it's a bit too soft. But for your .44 Rus. & Special, you don't need very hard lead either. If you can obtain wheelweights..these are fine as is..though I like to add a bit of tin..in the form of 50-50 solder, this helps the metal flow better, and improves mould fill-out. If you can salvage back-stop lead this is also good..This is what I mainly use..again with a little tin to aid casting. If you do have pure..or soft lead.you could mix in some wheel weights to harden, or add tin..probably for light target use and plinking a 1-20 to 1-15..by weight of tin-lead would work well. To make an alloy of say 1-15..Which by the way was Elmer Keith's favorite..and you know he liked HOT loads. weigh out 14lbs. soft lead & weigh out 2lb. 50-50 solder..those spools you see in hardware stores are 1 lb. Now then, the 2lbs. of 50-50 is 1lb. tin & 1lb. lead. the 1lb. of lead with the 14lbs. you weighed out makes 15lb. plus your 1lb. of tin= 15 -1 lead/tin alloy. Best of luck..and be careful!
