Sweet, that's good to know. Sierra bullets seem to be much easier to develop consistant accurate loads for, plus mag feeding can become optional due to jump tollerance. The Berger VLD's are quite a bit longer than SMK's of the same weight, requiring a faster twist to fully stabilize. In fact I've found that BC is often a better indicator of needed twist over bullet weight. The 190gr SMK has a BC of .533 vs Bergers 190gr VLD's BC of ..574. Barnes Greenhill formula is a safe bet when in doubt. Although you can often get away with a slightly slower twist.
Here's a line up of a few 308 bullets I've used (sorry it's blurry).
They are in order of weight from left to right 155gr Lapua Scenar (.508 bc), 168gr Hornady A-max (.475 bc), 170gr Lapua Lock base (.525 bc), 175gr SMK (.505 bc) and the 185gr Berger VLD (556 bc).
