I.D. of projectile ? (discussing 7x57 Mauser or 8 mm or ?)

Hi, difficult for me to see one 7 mm …

It need to be mic’d close to the tip away from the fired end which would be slightly compressed by the force of the round going off. There is an indication of distortion based on the non-linearity of the bullet sides in the photos. Overall, the impact into the dirt/ground etc is going to make the accuracy interesting to determine. The minimal diameter is probably the best example of the actual bullet size?
