I'm right with you on figuring this out, but I think you have to consider that the more jump you have, the less case capacity you have. Less case capacity = higher pressure for a given amount of powder, equals wasted potential. Check your Berger manual for another article by Litz that talks about taking advantage of longer throat lengths - the longer you can load your bullet before hitting the lands, the more case volume - larger volume allows increased powder charge (and velocity) without increasing pressure as much. The lower you seat the bullet into the case, the more you reduce the theoretical maximum velocity for the components you select. Ideally, I *think* you'd like a powder that fills the case 100% and burns 100% as the bullet travels down your bore, yields maximum velocity over all other powders with an acceptable pressure, AND that such a recipe yields a bullet velocity that miraculously equates to your barrel's natural harmonic "node." If I could get those variables to line up for all my rifles, I think I'd be cooking with grease...I suppose you could offset the lower case capacity with a faster burning powder? I'm over my head though...
On the other hand, when you go the opposite direction and seat a bullet into the lands, you can create a pressure spike, or so my reloading manuals tell me (including the Berger). Wilderness Means suggests always developing max loads with bullets seated .01" into the lands for this reason - good info on his web page, just Google.
Bottom line, if your case neck goes beyond your bullet's ogive, I'd say you went too far
If anyone sees anything "crazy" in my spiel, please advise and correct! Good luck!
