[QUOTE="tnek13, post: 1728706, member: 43112"] Concentricity is important. If you do not measure it you just don't know if the bullet travels straight into the lands. Standard seating dies can do a creditable job, Forster Ultimate seating dies do a great job of getting the bullet straight into the case. Bullet pull consistency is covered above with the expanding mandrel and even the Lee die, but crimp is not always necessary or desired depending on the type of rifle. Shoulder set back is obtained by setting the sizing die to bump the shoulder.001 thousandths or so for a bolt gun. You don't mention the rifle type, caliber, barrel twist, bullet type, or powder, these factors matter, you said you chose quality components so I will assume you have chosen wisely. One last thing, when testing for groups take your time, make sure your hold, shoulder pressure, rest, trigger pull, etc are consistent as well as your scope solid - I only throw this in because last week I got really frustrated until I found that my scope base had loosened, my fault but as careful as I try to be stupid things happen.
