OAL Variation from specific manual dimention +/- ?
Quote from Xiphos on October 1, 2023, 7:24 pmThe published OAL for any given cartridge allows for chambering in any SAMMI specification chamber.
Seating a projectile too far out and engaging the rifling can dramatically increase chamber pressures, read: "DANGER!"
Tools are available for determining the distance from the projectile's ogive (front curvature of the bullet) to the landings. These are designed to accurately set projectile seating depth (I.E. Hornady).
In many magazine-type firearms, setting OAL too long will introduce feeding issues. If set long enough, you may not be able to load the magazine(s) properly.
You can't go wrong with following published data.
