I am shooting 190 VLD's in my 300 wsm. I went through a box of 100 before I got it to shoot like I wanted. Tried 3 different powders and different seating depths. Finally settled with H4350 seated .03 off the lands. Shoots one hole groups at 200yds. Thought I had it nailed and everything went haywire. Found a screw loose on the back mount and was throwing shots off about an inch. Check and torque often and use Loc-tite.
