It's common practice to work up a load with the projectile .010" from the lands. After a good load is found, more hairs may be split by adjusting that bullet jump, in slightly, or out.
I should have wrote "It's common practice
for me to work up a load with the projectile .010" from the lands.
Just starting out and considering that you are working up hunting loads, it might be best for you to begin by working up your loads .020" from the lands, if you decide to start determining O.A.L. in this fashion.
