Thread: Projectile shifting in neck once loaded?

The ogive of the bullet changes with changes in different lots of bullets (despite the best intensions of manufacturers). The bullets are made on different machines/dies and mixed up so there will be slightly different ogives in each box of bullets. Measure the ogive to base length which is the relevant measurement for the chamber. The overall length (OAL) is relevant to the cartridge length which must fit into the length of the magazine.
