Funny thing though my ammo made for the .223 savage axis i seat the 55 v-max to 2.275" and can go more.
But a 5.56 AR i have will not allow that long seated bullet to chamber all the way.
So that got me to thinking about headspace and lands position.
Headspace defined.
The actual headspace of any firearm is the distance from the breech face to the point in the chamber that is intended to prevent forward motion of a cartridge.
That would be to mean the shoulder Ogive
Now distance to the lands is something completely different.
