Mix it about 40/60 to 50/50 with pure lead and all is good. That is, if a bullet caster doesn't beat you up and steal it for himself. LOL. Linotype is getting pretty scarce these days and it seems to be a prized possession. I'm sure a few shotmakes will chime in here.
Linotype contains a percentage of tin for reducing surface tension, GOOD for bullet casting as it helps fill the sharp corners of the bullet mould. NOT good for shot making, surface tension is what makes the shot pellets nice and round.
Lyman lists linotype as 84% lead 4% tin and 12% antimony with a brinell hardness of 22 and Lawrence shot as 92% lead 2% tin and 6% antimony and the brinell hardness of 15 They also list if you mix linotype 1 to 1 with pure lead you will get the ratio's of what Lawrence shot is made of.
