Playing with seating depth

[Klem]

In an AR I doubt if you are going to see any noticeable differences in group size that you can guarantee belongs to seating depth. The system is just not precise enough plus the mag limit stops you from experimenting seating closer to the lands where if there is going to be a difference this is where it will be.


Maybe mag limit and one OAL shorter but anything shorter is robbing you of velocity. Varying bullets and powders is enough for me.
