We get calls on the tech support line and support emails all the time from shooters that try to use the same bullet seating depth testing procedures on our Hybrid bullets as our VLD.
The Berger Hybrid bullets have both the VLD (secant) and Standard (tangent) ogives incorporated into the nose design. This makes these bullets very tolerant of jump in most cases. As a result. I suggest that you start your bullet seating depth testing with the Berger Hybrid Target and Elite Hunter bullets at .015 off the lands. Then work back into the cartridge case in .015 increments. Once you find your bullet seating depth accuracy node and want to see if you can “tweak” more accuracy out of it. Test at .002 to either side of that bullet seating depth. Between .015 to .060 off the lands is where your bullet seating depth accuracy node is usually found. There are always exceptions to any rule though. So if your bullet seating depth accuracy node is not found going away from the lands. You may want to start at .015 off the lands again and work towards the lands in .002 to .003 increments.
Information on the effects of bullet seating depth can be found here.
When doing bullet seating depth testing your moves are always based on the CBTO (Cartridge Base to Ogive) distance to the lands! Never use the COAL ( Cartridge Over All Length)! This measurement is only used in regards to cartridges that are loaded to magazine length.
