Since I can no longer find my preferred projectile, I went to the range yesterday to test a ladder loaded with a projectile that is available. I loaded 5 cartridges each at 4 loads from the starting charge to just below never exceed charge. All 5 loads cycled correctly EXCEPT at 2 different charges, one of the 5 failed to fire. Each of the non functional cartridges were neither the first nor the last cartridge in the magazine. The 2 non functional cartridges had no evidence of any strike on the primer whatsoever. At each FTF I reloaded the cartridge into the magazine, chambered it and attempted to fire with the same result. The only commonality was that they both had a slight deformation of the copper jacket at the case mouth, suggesting the bullets were over crimped. However, when I returned to the loading bench, both cartridges slipped easily in and out of the case gage. Particulars below:
