107 SMKs and VVN150 info please

[ShootDots]

Hi Guys.. I just ordered a few hundred 107gr. SMK's and some VVN150 powder for my 6mmBr. My 6mmBr is a BAT action, 1-8 Krieger (28") throated for 105 BT's. It is a NO TURN .272 neck. I would like this rifle to be my 600yrd F-Class "Open" rifle. I have read everything from seating the 107's 10K into the lands to 20K off the lands. It has been my experience with my 308 that 5-10K OFF the lands has worked with every SMK I have tried in that rifle. Does anyone have a "Good Starting Point" (seating depth) for those bullets? Also I have NEVER worked with any VihtaVouri powders. Does anyone have an idea of where to start and what may be my practical max load with that powder and that bullet? I certainly appreciate any info y'all could help me with... Thanks Guys!

well, with my 6BR shooting 107 sierras, i found that seating the bullets .020 ITL gave me the best es/sd. for about the first 100 rounds of the barrel's life, i was seating the bullets .010 off the lands. dissatisfied with the sd/es, i began playing with seating depths--just touching, .010 ITL, .015 ITL, .020 ITL. the latter gave me single digit sd and close to single digit es with phenominal accuracy. as far as the powder goes, i cant help you.

Don't have any experience with VV150 but my brother shoots VV140 with great success. Velocity and accuracy are excellent.
