Is that like a br case?
Good brass like lapua is pretty good. I have done all that but it didn't make any noticable difference to me, then you will need to weigh projectiles, if all the hype is to be believed. Sure sometimes I cull the extremes if I'm wanting to rule out all possiblities however.... For me what I found more important was neck thickness, turning, tension, anealing, seating, concentricity and a good rifle.
A well developed load you won't notice a slight difference in case volume, let's say a few kernals of powder.
I use a neck thickness gauge I think it's called, but it takes a consistent feel for it.
