Bullet Seating Depth - How to know?

[philw]

Have you got your powder charge figured out already? Best to get that squared away before playing with depth IMO.

+1 on that.

If your mag box won't allow you to seat the bullet near the lands and the bullet is 80-100 thousanths or more off the lands, then varying the seating depth is not going to make as much of a difference on group size as varying the powder and charge weight.

Or even the bullet.
