To determline where the bullet ogive touches the lands, get a Hornady bullet comparator and read the instructions. The lighter bullets may need to be seated down so that they are not able to reach the lands. Try to keep minimum of about .01" of bullet in the neck.
There! this is the comment I have been waiting to see in this thread. All other discussion had proved fruitless for me
until i got one of these babies.
And the Barnes bullet company insists that the ogive of it's projectiles be seated 50+ off the lands, and this simply can not be done on a replicable fashion without one of these gizmo's.
I find that my hunting guns prefer the ogive of the bullet to be 10-20 thou. off the land. In fact, the more powder I stuff into a case, the more i will back the bullet up.
this one tool has been the best investment in reloading stuff i have made for consistent shooting while switching up projectiles.
as for how deep to seat in the neck, if the entire neck surface of the case is not engaged with the bullet, i don't do it. Again, it has to do with consistency. statistically, there is very poor consistency with case/bullet friction with only 100th" of the bullet in the case mouth.
No, I am not a math prof nor an engineer, however a lot of shooting buds at the club are and i deem them worth listening too as these old boys can shoot circles around me.
good shooting folks!
