usually go .01-.02 over bore diameter for your sizing die. Top punch will depend on the style of bullet being used lyman and rcbs usually list top punch style needed for each bullet most guys though just make themselves a flat one and use it for everything but the round nosed bullets. Yes it will seat gas checks make sure there on square though before you run them through the sizer. they will be crimped on (if you buy good hornadys not the lyman crap) when you run the bullet through the sizer.

Slug your bore and throat with lead sinkers [oval egg] and measure with a quality Micrometer that you or your mechanic would own. Buy your sizing dies .001 larger than that measurement for best accuracy. Gianni.
