I have used both the 168 classic hunter and the vld. I found that the classic hunter could be seated anywhere from .010 to .090 off in my 7RM and be accurate, it did not seem to really matter. Now grains of powder/velocity made a big difference, but seating depth really didn't. With the vld there was defiantly a difference when I tested seating depths, but I have not had to change the grains in H1000 to remain accurate. They both however shoot very well, and I have taken game with each. I did not see much of a difference in expansion, they both did what they were supposed to.
In a 7RM I am able to fit either of them loaded into the lands, but I do not think you would be able to load a 168 VLD into the lands with a 7stw unless you had an extended box like a wyatt's. With that being said, I have read where the 7stw likes a jump anyway so this really does not matter.
