    New BH 5.56 mm 50 gr TSX initial data

    Below is some data from the new BH 5.56 mm 50 gr TSX load.

    5 shot averages fired at 3 meters from 14.5" M4 w/ave MV of 3012 fps:

    BG: pen=14.7" RD=0.47" RW=49.9gr
    Steel: pen=19.4" RD=0.22" RW=49.6gr
    Wall: pen=16.7" RD=0.46" RW=49.9gr
    Auto Glass: pen=17.0" RD=0.36" RW=43.4gr

    ----------

    MV from various barrel lengths
    8" = 2634 fps
    10.5" = 2749 fps
    14.5" = 3105 fps
    20" = 3205 fps

    One of the nice things about this load is that it works very well in barrels from 8-20 inches long and works in twists from 1/12 to 1/7.

    The photo below compares a 3m BG shot from a 10.5" brl on top with a shot from a 20" brl on the bottom:


    Below are some recovered bullets fired from an 8" brl into BG at 3m:

    Impressive results. Does the 50gr TSX still exhibit petal shearing through auto glass like the previous TSX bullets?

    A bit, but not as bad as before.

    Have you guys called Black Hills (800-568-6625 ) and asked where to get the ammo? I have recently been informed that www.firststopgun.com (605-341-5211), a store in Rapid City has the new BH 5.56 mm 50gr TSX in stock.
