MK318 SOST | Ballistic Gel Test
This video details a ballistic gel test of MK318 SOST ammunition fired at a reduced velocity. The test aimed to replicate previous M855A1 testing by loading the MK318 over 21.5 grains of RL 15 and firing it from a 14.5-inch M4-style rifle. The results showed significant fragmentation and disruption, with the bullet core recovered after penetrating multiple gel blocks. The speaker estimates the reduced velocity to be around 2450 feet per second, consistent with fragmentation thresholds for this ammunition.
