I've had GREAT results with the Berger 168 gr. VLD, I use BL-C2, 43.5 Grains.
I've also run as hot as 44.5 Grains with great accuracy.
I've got a Krieger barrel with a 1:13 twist.
Play with your seating depth, sometimes a bullet likes to have a .015'' to .020 jump before it hits the lands of the barrel.
Very often, good accuracy comes when a bullet starts right up against the lands. BUT, this is not always true, sometimes backing them off the lands and letting them have some room to jump helps.
Good luck!!!!!!!!!!!
