Had fun today shooting for a German Keilernaedel with my M1910. I did have some rather old Kynoch ammo to play with. I'm assuming it was from the 1950s or later, as the box was clearly marked "rust free caps". I'm thinking that means non-corrosive primers.

In any case, all went well, except recoil was much more than the Dorfner rounds I was using earlier. I would have loved to have had my labradar with me, as I wonder if I was also picking up velocity to go with the added recoil. One thing I did notice as I got ready to load my last round: I noticed the previous round had a slightly split case. I then looked closely at the others, and noticed several. I thought it a little odd, as there were no other obvious signs of pressure: the primers were not "mushroomed", the base of the case was fine, etc. Just some minor splits. Not good at all, as I was hoping to save the brass for reloading.

I never fired that last round. No real reason to risk it. I'll pull the bullet, burn the powder, etc. Definitely not re-using that brass though.

Yes, I did get the needle!
