I have a some confusion about bullet seating depth I hope I can get cleared up. For the most part I understand about measuring to the Ogive and backing off from the lands. When I measured with hornady chamber gauge my .308 with hornady 150 gr fmj and it my initial measurement to the lands was 2.251 with the ogive of the bullet. So then I backed off the lands .020 so then I made the bullet 2.231 that I get I believe. The part that confuses me is that I checked to see what the OAL was just to see where I was at and I was longer than the 2.810 which is the basic OAL given in the load book I use for reloading. Does that measurement not matter as much now that I am measuring to the ogive and as long as the bullets seat in the magazine? I know this is a lot to take in but I just don’t want to seat the bullet too far out.
Thanks for any advice!
