The reason for the recommendation against litho had mostly to do with accuracy. The author said using Lyman alloy (i misplaced the post and cannot say which alloy he used) brought him very tight groups, much better than linotype.
I just looked, Lyman #2 is 90% lead, 5% tin and 5% antimony. Linotype is very high in antimony and expands upon cooling. I don't know if that has anything to do with the difference in performance.
Just for grins, I cast a number of 200 grain .30 cal bullets from lead that came from old soil drain pipe and wet cell car batteries plus about 1% tin and sized them with gas checks. It was cold out in the shop, and i did not think to first warm the lubrisizer. SKRUNNNNCHH! Oh my, how those bullets get short in a hurry.
Once warm, the sizer functioned just fine. I measured the bullet length before and after and they were OK.
It's supposed to warm up tomorrow here in Ohio, and I will be able to tell you how they work in an '03-A3
