PP'ing 338 boolits. What size to start with?

[AJ Peacock]

OK,

I've read and read and read and searched but haven't been able to find the answer (I think [smilie=1:).

I've been casting 220gr .338's and sizing them GC'ing them. I am now contemplating PP'ing for the rifle.

How far undersized should a boolit be before you start PP'ing them? Lee makes 2 potential push through sizers (.323 .329), The reading I've found so far points to around .007-.008" PP increase. So the .329 would patch up to .337" or so, which is a tad too small.

Would the .329 be too small? Or is it typical to patch up more than .007-.008" ?

Could I get the .329 and polish it up a couple thousandths?

Thanks for any info,
AJ

Slug your bore. Size the bullets to bore diameter +.001/.0015. Wrap with 16# paper, I prefer the printer with holes on both side to feed through a printer, it seem to be a little tougher. Let dry, lube, and push through a die that is .001/.003 over groove diameter. Load like jacketed and go shooting. A .327 die can be lapped out to the size you need in just a few minutes.
