I use a Hornady/Stony Point seating tool to find WHERE my bullet contacts the lands. Or how far out can I seat a particular bullet before contacting the lands.
With the 130 Berger VLD's I contact the lands at 2.770" overall cartridge length. VLD's tend to like to be JAMMED, or in contact with the lands....So I tried .010" longer at 2.780" to get .010" worth of jam. or INTO the lands. Forgive me if my terminology was confusing.
Contacting the lands can l also raise pressures so best to back off a few 1/10 ths of a grain and evaluate where your at pressure wise.
