I don't shoot Berger VLD's, therefore, I can't answer your question directly. But I can offer some of what I learned when developing a good competition load for my 6mm BR Norma. I stay away from the 105gr VLD because the thick jacket produces a less-than-perfect meplat which (in my opinion) requires both trimming and pointing. I prefer the VLD Hunting version since the thin jacket makes it easier for Berger to produce a better formed meplat. I believe the two bullets are close to the same shape. But I only shoot the VLDs when I can't get the 105gr Hybrid bullet.
The Hybrid is significantly different in shape and is my preferred 6mm bullet for 600 yard BR or F-Class. It has a higher B.C. and seems to be quite a bit easier to tune than the VLD's.
Here is a chart showing a few of the bullets I've tested in the 105gr to 110gr range. The data represents the average of the best five of the 5 shot groups (25 rounds) of each type shot from a bench using a 28" 1:8 twist, Shilen Match Select barrel on a Savage Target action at 100 yards in still wind conditions.
Each different bullet seems to have a preferred powder including Varget, IMR 8208 XBR, CFE-223, Vihtavuori N-140 and IMR-4895. However, the Berger Hybrid shoots well with several of these powders; i.e. unlike the other bullets, the Hybrid doesn't exhibit a preference for one particular powder. The Hybrid also is less picky about charge weight and seating depth.
For those not familiar with ATC (Average to Center), it's the same as mean radius, a measurement which is tedious to calculate by hand but one which my On Target software calculates automatically. Some folks, including me, think that ATC is more meaningful than MOA when it comes to judging how well a particular recipe will do in competition.
The poor performance of the SMK 110gr bullets is a result of my 1:8 twist barrel. Sierra says a 1:7 twist or faster is required and after a bit of testing I believe them. It's a long, sexy looking thing, but I doubt if I'll do any more testing with it. The new Hornady ELD is also a good looking bullet. It's shorter than the 110, but has that perfect plastic tip which appeals to the aerodynamicist in me and may warrant further testing, but it most likely is best shot out of faster twist barrels. As you can see, the Berger 105gr Hybrid is the performance stand out. Of course, YMMV.
