Sizing down .004 -- in a mark VI

[fullofdays]

I've got some 150 Gn .360 hard alloy SWCs laying around and am going to resize to .356 in my mark VI lubrasizer to load for 9mm. Can sizing down .004 be done on a mark VI? Any tips for not jamming a boolitt in my .356 die?

Try .358 and see if they will chamber. If not willing to do that, then just make sure you run a lubed bullet through the sizer every 5-10 bullets if they start getting difficult to size. With some soft alloy I have sized .454 down to 429. Didn't do it on purpose, but my Star took it OK.

Works a charm. The bases have lead hanging all over em.
