FMJ yaw and upset performance

[DocGKR]

Well, working at a Level I Trauma Center often results in somewhat unusual hours...

This week someone asked me about the misinformation posted in this thread regarding our initial SPC testing, so I thought it might be prudent to provide the correct facts.

Some of the characteristics of an ideal performing general purpose rifle projectile have been described in recent government wound ballistic meetings and in commentary by SSA Buford Boone of the FBI BRF:

-- Penetration of 12 to 18 inches
-- No impact AOA induced variations
-- Blind to barriers
-- No deviation from shot line after impact
-- Minimal fragmentation
-- Consistent terminal performance from 0 – 300 meters
-- Sufficient accuracy to hit threat targets out to 600 meters

Assuming properly prepared, calibrated, and sized gel blocks, I'd be supportive of any Grendel load that meets the criteria listed above and offers barrier blind terminal performance, as depicted below:



Keep in mind that “Barrier Blind” ammunition should demonstrate minimal changes in terminal performance between unobstructed shots into bare gelatin and those obstructed by intermediate barriers.
