[QUOTE="barefooter56, post: 1079569, member: 85389"] ajridgedell, Wow! .020 in 300 rounds. It took a years worth of practice and competition for my .308 to move out .010! One thing I found was that if my rifle liked the bullet .010 off the lands ( just an example). Keeping the bullet .010 off the lands as I chased the throat kept me in my seating depth "sweet spot. At a certain point though I did have to tweak the powder charge to keep me on the velocity accuracy node as the bullet moved out and resulted in more room in the cartridge case that affected the pressure/velocity. The only problem is that sooner or later you run out of bearing on the bullet in the case neck and have to screw another barrel on and start all over. Its a vicious cycle. [/QUOTE]
