A few years ago, my boss gave me two cardboard boxes of three 10rd stripper clip 5.56 cartridges, marked "BLACK HILLS AMMUNITION - 30 CARTRIDGES - CAL 5.56 - 87 GR BARNES PROJECTILE - LOT #BLH09B168-001" with an '07 Lake City headstamp as a Christmas gift. I gave one to a friend and kept the other. They are open tip projectiles and will fit a magazine, but I don't want to pull any down or shoot them to find out what they are / how they perform, since I've found nothing informative about them in a few quick searches / in the archives. Does anybody know what these are / were? |

I remember seeing some experiments with those Found an old thread. Stands to reason Black Hills played with it too. |

You should email Black Hills |

When you are testing projectiles, you need to eliminate all variables in cartridge construction and load variation. So, it makes sense for a single facility load all the ammunition, and if the military is doing the testing that facility will probably be LCAAP, even if the cartridge itself will be commercially procured. The ammunition would be loaded with cases, primers, and propellant from the same lot, and of course would have to be marked in a manner so the testers could easily use (stripper clips) and identify the ammunition. What you had (or have) is a sample of the ammunition that was to be used in that test. And, I believe the eventual winner was the 77 grain SMK. Probably, cost had a lot to do with it. |
