8mm lee push-through sizer?

I want to cast 8mm bullets for my k98 and kraut-cano. The only lee pushthrough sizer they make close to that is .323 ("true" 8mm), I have always been under the impression that cast bullets needed to be .001 over (.324 in this case).

Should I get this and run some dummy bullets with lapping compound on to try and open the die up .001? or will a gas check mitigate the problem?

eh, just checked my lyman cast bullet book, under the 8mm mauser load section it says sized to .323 and gas checked. Probably should have started there :headslap:. I'll go ahead and order the sizer/mold.

I have used hunter's specialty 8mm bullets that were sized to .324 in the past, so I thought thats what I should do when starting to cast my own.
