I panlube to the stopring.

With smokeless you dont really need the front lubegroove filled.

I normally push the bullets out of the grease from the front but with the stopring it creates a lube mess and a lot of whiping. Pushed out from the rear they have nothing more than lubed grooves and needs very little wiping.

I use Mikes method for half a dozen calibres, despite having a lubrisizer and dies for many of them. Ten years ago, I conducted a series of bench rest tests----unsized bullets , tumbled in liquid alox, beat the lubrised samples every time.

Since we don't need to size stop ring bullets, an aluminum "sizer" die is easy to turn to fit a Lyman or RCBS lubrisizer. Four holes drilled from the groove on the die to up near the die mouth will transport lube to the grooves on the bullet shank, and reverse the bullet to get the groove on the nose. The stop ring will position the bullet in the die - don't apply pressure when seating the bullet. The same sort of process can be used with a brass or aluminum die fitted to a particular tapered bullet. Drill lots of lube holes adjacent to the bullet grooves and back off the lube pressure before pushing the bullet out. Done correctly, the grooves are filled consistently and it doesn't take a lot longer to do than the usual sizing process. You can even make a die set for your Martini Cadet to fill the single groove in the nose.
