I recently purchased a slightly used HK VP9SK at my LGS for a song. I cleaned it well and lubed it appropriately. Today, I shot Winchester white box 115 grain ammo, Winchester NATO 9mm 124 grain ammo, Winchester USA Defense 124 grain +P, and some old Remington Golden Saber 124 grain +P loads. All of it was factory new when purchased.
The gun performed flawlessly until part way through the third magazine of the white box rounds, when it suddenly would not go into battery. I removed the magazine and cleared the round from the chamber. It looked fine. I later loaded this one round alone in a magazine and tried it. Again, it fed but would not go into battery.
I set it aside and burned through a bunch more ammo without a problem. Once home, I did my best with my caliper to measure the round. The diameter seemed to match other factory rounds I had. But, when I measured the case length, it was .762 to .768, depending on that point in the circumference of the case. I measured a different white box 115 round, and it was .748. My Hornady manual shows the case length should be .754 inches. I am glad I did not force the round into battery and make a high pressure situation.
Have any of you had this happen with Winchester factory loads?
