I only have two Cadets, One "converted" to .32-20 WCF and one original, and both shoot more accurately with the addition of the wax-check. Recovering fired slugs revealed the wax adhering to the bullet base so I began inserting a typing paper wad to prevent this. (My 3-ring binder hole punch supplies them in abundance) I am casting of AC/COWW + 2% tin with a 320/120 CBE mould and lubing with LLA. The heeled portion appears to be fully expanded into the rifling with zero evidence of gas leakage when the wax checks are used. This is not the case without them.
