not sure what I done ,after reassembling the 357 max from the blueing I did the traditional test firing and she flicks out the 357 max empties like a hot dam !
only thing I will guess was I like the breech block polished and shiny so when polishing it up may have removed just enough or slicked up the block that she works

yes they are fun projects to build up ,here is a pic from the first day of deciding to start projectile parts are on top of the stock board
