RCBS bullet mould seconds?

[fatelk]

I recently bought a couple bullet moulds, leftovers from an estate (cheap). They are RCBS, one set new in the box, the other used. The question I have is that they are marked "Second". The box is stamped across the top and bottom and both molds are stamped on the side.

Normally when I think of factory seconds I think of something that is blemished or damaged, imperfect in some way. I can't see any problems at all with these. I guess I'll just try them and see how they work.

Has anyone used RCBS factory second moulds? Any problems to look for?
Thanks for any info.

I say cast a few and check their drop weights and sizes. I know they have a over/under spec for both size and weight but that doesn't mean they wont drop perfectly good bullets.
