Test Gun: Smith and Wesson model 65. Barrel length: 3 inches. Ammunition: Liberty’s .357 Magnum 50gr Civil Defense. Test media: 10% Clear Ballistics Gel. Distance: 10 feet. Chronograph: Caldwell Ballistic Precision Chronograph G2. Five shot velocity average: fps 1796fps Gel Temperature 70 degrees. This is an interesting round that consists of 50gr all copper bullet with a large hollow point. The idea was the bullet would fragment early upon entering the target. The hollow part of the bullet breaks off into smaller pieces and radiates away from the main path of the bullet core which would then driver deeper in the target. Using the S&W M65 I got an average velocity of 1796fps with a high of 1860 and a low of 1746fps. Liberty list this load’s velocity of this round at 2100fps but doesn’t list a barrel length. The point of impact was about 3 inches low at 10 yards. 
Five round offhand at 10 yards. Point of aim was at #3 The first round in the bare gel exited the top of the block at the 7.5 inches mark. No velocity was recorded and the bullet core was not recovered. The fragmenting portion of the bullet started at about the 2.5-inch mark and stopped at about the 3.5-inch mark. The weight of the fragments was 10.1 grains. The second round’s velocity was 1786fps and the core penetrated to 16 inches. The fragmentation was 2 to 4 inches deep and the weight of the recovered fragments was 6.3 grains. The recovered weight of the core was 36.2 grains. 
In the covered gel, the first round had a velocity of 1716fps and the core penetrated to 12.5 inches and weighed 36.2 grains. The bullet fragments 2.5 to 3 inches and had a recovered weight of 16.8 grains. The second round’s velocity was 1718fps and the bullet’s core penetrated to 11 inches and weighed in at 36.3 grains. The fragments went from 2 to 2.5 inches and weighed 10.5 grains. 
The fragments from all loads spread from 2 to 3 inches from the main bullet path. https://generalcartridge.wordpress.com |

Their 50 grn 9x19mm should be interesting out of a 16" SUB-2000.
Wish they had a FMJ, though. |
