Been reloding for a while,but have not played with loads having the bullet into the lands much.

How does one go about finding the powder charge for seating the bullet into the lands..I mean
actually touching the lands....Thought maybe this would increase the accuracy of my rifle.

I will be using the Hornady 55 grain v max,as I have a lot of these bullets...And probably
use H=380 as well...Maybe H4895 or Varget....Thanks
