I recently acquired some Linotype I'm mixing with soft lead and some range scrap I have. I haven't had any tested so I don't know what the alloy actually is, but my cave man testing tells me it will bend some than snap. The lead I have will bend but not break.
I thought I'd do some experimenting with the lead I had in my pot. My 20 pound pot was about half full of the soft/range scrap. I didn't weigh it, but added a hand full of the Linotype and cast a hundred or so 125 grain boolits. They came out nice, perhaps slightly better defined than the soft/scrap boolits I've done in the past. Today I added enough Linotype to fill the pot about half full again and cast a 100 or so more. These also come out real nice, perhaps slightly frosty (PID controlling temp. 712* F). With these I noticed the sprue cuts way easier than before. A very slight tap and it's cut. I haven't tried any yet but I'm guessing they are quite a bit harder than the last batch.
Question... Can I add too much type? If I got to *pure* Linotype will it cause problems? How do I go about finding a good mix?
A bit more information.... Right now I am only casting for 38/357 and 9mm. Since I started powder coating I have zero issues with leading, even with the soft lead I've been using. In the future I plan to cast for my 30-30 and '06 mouse fart loads.
