I have searched, googled, looked high and low for real velocities from this load in shorter barrels (10.5" is what I am looking for, the closer, the better). The "shortest" I have found is 16".
Also, has anyone tested this round for accuracy from an SBR, and does it perform better than the 70gr offerings? Thanks in advance! |

Eric802,
Got those numbers for you. HK 416D, 14.5" barrel, velociity 2,784fps, SD of 10 LMT, 16" barrel, velocity 2,911fps, SD of 18 DPMS, 18" barrel, velocity 2,990fps, SD of 8 Custom 20" barrel, velocity 3,029fps, SD of 9 These results are what we received through these weapons today with one lot of ammo. YMMV. |

YMMV. What is the minimum velocity for expansion ? |

Wow! Interesting. I am guessing heavier = faster? |

So technically is does not make it faster, just more effecient. P |

He meant that he no longer had to stress over minimum frag velocities as he now knows of a more reliable mechanism and product with a much larger performance envelope. |

You can then sort the columns by name or weight to find the match ammo more easily. |

Stuff like this is why I buy BH.
And on topic: Thats some impressive expansion ranges for the 62gr pill. I'm gonna have to get some for the longer barrel guns. I use 50gr TSX on anything under 14.5" |
Referring to me: you have a very sarcastic and condescending and patronizing and insulting and demeaning way of 'being helpful"
Just the right amount of wrong.
