How is it Berger VLDs are seating depth sensitive and the Hybrids aren't ?

[Ironworker]

Just ordered some Berger 105gr Hybrid What is the difference between those and their VLDs and how is it possible to increase the BC of the hybrid over the VLD ?.................. A shooter on Long Range Hunting claims with burning the new Re#33 in a 6/284 is producing 3450+ with these hybrids out of a 27"bbl I wonder how fast I can push them out of my 30"bbl ?

The area at the ogive-bearing surface junction is changed from a secant style ogive to a tangent style ogive for a first portion of the ogive giving a more gentle approach to the rifling as compared to a regular secant(VLD) ogive. This small change of the profile of the bullet makes it a small bit longer hence a higher b.c. I recently started working for an engineering firm and am trying to figure out tangents and the like myself.........

The Hybrids have a slightly lower BC than the VLD.

There is no Berger VLD that has a B.C. higher than a Hybrid of equal weight. The Hybrids are all higher. [br]

Well, that's interesting. Those two and the 185 grain, caliber .30 Hybrid and VLD Hunting bullets (G7 .280 and G7 .281, respectively) are reversed from all other Hybrid/VLD pairs. I can only speculate that it must have something to do with hunting performance. I admit that I only look at Target bullets, where the advantage favoring Hybrids is small to significant.

The classic hybrids are made to comply with SAAMI requirements for general use with commercial and hunting ammo, etc. and they are a lot more blunt in the front and have lower b.c.'s.

The slight change in the ogive is intended to make the bullet easier to to find the sweet spot for the reloader also. One of the shooters on Longrangehunting.com used the 210 or 215 in his 300 win mag to experiment on game this season with outstanding results out to 1200 yds. I'm having a hard time finding the 6mm or 7mm in South Carolina. Hope to try them for 2013 season. Still love the Amax!
