Afraid that the only way to know FOR SURE is to..................... Bang bang...
Your barrel(s) will tell ya... Wether 6, 7, 7 1/2, 8 ogive etc... experimenting by seating the ogive to Jump or In lands..
IMOP.. >GOOD< bullets don't care... Ok well what I mean is within a reasonable range of throat seating depth.. Again, IMOP... From around .008 in the lands to as far as .020 jump...
Typically like most, I like a very light mark on the bullet.... But... In cut 4 groove barrels, I find that seating juuuust off a mark, say .002 off the mark tunes REAL well and Important to me... I can chamber a round and remove it without disterbing the seating depth.... Good during the HOT summers day matches and hot chambers... If ya gotta stop, you can back that round out without cooking the round or inducing more heat in the chamber by firing it in a cease fire... Not to mention sticking the bullet and dumping powder.... Bummer.
The Euber dies that made these bullets more than likely produce very tolerant bullets .... Good guys as I call'em.! If you have these bullets on hand, head off to the range soon as ya can.. If your thinking on a purchase, Buy'em...!
Honestly a 1/2 to 1/3 deep land mark as the lands width should get you to a steady tune.. Little powder fiddling but a competitive tune should be found with this seating depth.
good luck,
