Lead prep

[angus6]

I've come up with about 300# of what I was told was High voltage wire shielding , it was really soft . What do I need to add to get this ready for casting 9mm
TIA

I would blend 50/50 with WW's, then add 2-3% tin. Or blend 50/50 w/lino. Either will give you a dang good alloy that your 9mm's will appreciate.

Or you could simply add 3% tin and have a good, aalthough lower speed, alloy.

Got about 40# WW guess I'll be scrounging some tin and give that a try

You could probubly shoot the soft lead and low velosity no problem, at least until you get some alloy.

Shoot the soft lead in low velocity pistol loads. Alloy it for higher velocity.

this is a 9mm guys, pure probably isn't your best alloy.
if it is all you have i would go with 20-1 first.
if you have some ww's cut in half and add some tin.
check your bbl diam too 9's have been known to run as big as 358.
