So I've got about 40 or 50 lbs I got for quite cheap of some sort of alloy that was said to be linotype alloy. The alloy is in long strips 24"long by 3/4" wide by .050 thick and wrapped about 20 at a time in brown paper.
I tried casting some rifle bullets from it and they kept coming out rather frosty looking compared to my usual fairly "dull mirror" like cast bullets. I measured the hardness on newly bought Lee ball and scope kit and it looks like it's a Bnh of 25'ish. I need to make a stand for the scope instead of my shaky fingers but it's not far off 25.
I'm seeing references that linotype is usually more like Bnh of 22. I'm pretty sure given the chart that came with the tester that my eyes are not that wobbly. Is 25 still kosher for linotype? And is it proper that it would come out a little frosty looking? I know that I turned up the heat to get good pours. At my usual lead temperature it wasn't filling cleanly at all.
If you guys figure that this is in fact a proper linotype I guess I'm going to use it more to alloy other softer lead where needed. Or I wanted to try some .30-30 lead loads for cowboy long range. The max pressure shown for lead that hard suggests that it may be a good fit for some .308 size fast moving rounds.
