Sounds good - Lyman 325gr. # 452651 - a gas check design - - Lee Precision, also a double cavity mould - # 451-300-RF - is a gas check design.

The Lee mould will most likely be around $25.00, with the Lyman mould around $100.00cdn.

Spray Lee moulds (or Lyman blocks) with MsMoly and no more sticking lead or misaligning blocks and beeswax is no longer needed on the beveled contact surfaces or hinge. The moly in the blocks also helps release bullets.

For case head measurements, #'s taken before and after are said to be necessary and on felt pen marks, as ANY expansion is important, whereas expansion on the web is normal - up to .008" on some cases fired in some chambers.

Cleaning black powder fouling from cases is painful - I agree.
