Make sure you get real lino.  I bought some very fine rules once.  The old printer even gave me a story about taking his lino to have it refreshed at a foundry, then taking the refreshed lino to another place to have his 2 pt rules cast.  (Rules are just lines, like the fine lines on writing paper).  I had some bad news for him, the place he got his rules at didn't use his alloy, and they were cast with something other than lino, cast with a machine other than a Linotype too.  The lino turned out to be about the same hardness as Lyman #2!  There is a wee bit of copper in most type metals, though it isn't mentioned in most of the formulas you find.  I've never really shot straight lino, the benchrest cast bullet shooters at Washtenaw used it.  Lots of Sb, it might be a bit brittle, but should work if the pressure impulse is slow.  Heat treating WW is another way to get more velocity out of cast.

Expect your bullets to be a bit lighter, depending on the alloy they were spec'd with.  As an example, NOE specs theirs with WW.  Their 311284 comes in at 214gr w/o lube or check.  I have some cast of the same alloy I mixed up for the 311365s that Paul has, they are only 204gr checked and lubed.  Since I mentioned those 311365s, NOE weight with WW is 196gr, but those are 186gr checked and lubed with my alloy.  Others like Lyman spec theirs with Lyman #2.
