Sealant at case necks

Good point, Contender, about the sealant.

If these are factory cartridges, the pulling job, with either inertia or collet puller, will be made easier if you "bump" the bullets just slightly deeper into the case. This breaks the asphaltum bond, and is accomplished by simply turning your seating stem in about one full turn.

BTW--If you have some old military ammo that's fit to shoot, but is more than a few years old, accuracy can be improved by this "bumping" process. It "unglues" the bullets from the case necks and makes for more uniform bullet pull. CAUTION, however: Seat the bullets only about 1/16 inch deeper. I use about 1/4 turn of the seating stem, but your setting might vary.

I've done this old military match shooter's trick only with 7.62 x 51 mm military ball and match ammo, never with .223 or 5.56 military.

Best regards,
Johnny
