Don't be dissappointed with 150 BC
The .277 150 Grain Berger VLDs do not have the same ogive as their other VLDs, which correlates with the lower BC. They did this so hunters would not have to seat the bullets at, or into the lands to achieve the same results as with other VLDs, such as the 7mm 168. Why they called them "VLDs" I do not know, b/c they have more of a tangent ogive v. a secant ogive. No disrespect intended towards Berger at all, but, I think it would be less misleading if these .277 VLDs were simply called HPBTs. After all, I do not recall any .277 calibers at benchrest competitions. These bullets were added to satisfy the hunting crowd.
I personally have been extraordinarily impressed with their accuracy in my 270 AM. I have also found that you can, if you wish, treat the 150 VLDs the same as an Accubond or any other hunting bullet for test purposes, i.e., they do not have to be seated into the lands. But, seating bullets at or into the lands is my personal preference for most all of my loads, except for Barnes bullets.
