Sizing down .004"

[bcr]

I cast up about 125 HPs from my MP 434640. I bought the 434 because I have several .44s including a Browning 92, which requires a large diameter boolit (grooves 0.431"). They do drop 0.434" with 50/50 ww/pure.

I'm loading this first for my 696, which has 0.430" cylinder throats. I just sized a few of these with my Lee push-through sizer at 0.430" and the sizing die squoze the boolit so that there is a thin rim of lead left around the base of the boolit. I tried swiping these across some medium grip emery paper, but that seemed to make more of a mess of the base than I was hoping. What have other people done when they need to size down this much?

Lube the bullet with something BEFORE sizing. I size .311s down to .302 and .459s down to .451 all the time without that problem.

I size lubed .321 FB spitzers down to .314 for my Mosins using Lee Push throughs with no ring around the base. The only time I had a problem similar I had a new Lee sizer with a flat spot right at the end of the "pusher". It would allow lead and even checks to smear down into the void. Perhaps yours is worn around the entire edge enough to allow this? RD
