Hmm. No rifling marks on one of them. Those boys in Germany who have the million FPS footage of perpendicular, midair bullet collisions are the ones who amaze me.
Nice example. There were probably many collisions considering the millions of rounds fired, especially once machine guns were in use.
I recall seeing somewhere a photo of a civil war musket that had a bullet enter the muzzle and hit the projectile that had been fired and was partway down the bore. The bullets collided in the barrel.
A hundred thousand shooters with a hundred thousand rifles and machine guns
firing billions of rounds..... bound to happen.
I also noted that the one has no rifling. Probably a round hit a case of ammo.
Ripped the bullet out of the case it was in. Seems nearly 100% certain that cases
of ammo got hit in battles.
I had a recovered casting, an 8x56R Steyr bullet that was the NEI 331-245 IIRC, dead centered by another (jacketed) bullet in the berm. Pretty cool to find. I think I still have it in a drawer someplace.
