Matt from Demolition Ranch is back with one of the more uncommon calibers in his arsenal, the FN 5.7x28mm.
Designed by FN Herstal in Belgium, the 5.7mm is a bottlenecked centerfire cartridge that’s very similar to the .22 Hornet. The unusual pistol round was developed for use in both the Five seveN handgun and FN P90 PDW. With a bullet weight around 40 grains, the 5.7mm is lighter and faster than most other semi-automatic handgun rounds.
Matt had a great time stopping his .50 cal BMG with a few blocks of dry ice. Now he’d like to see what happens when smaller calibers are put to the same test.
For this experiment Matt compares the slow but heavy .45 ACP against the small but fast 5.7mm FN. He’ll also take a look at the 7.62x39mm and the 5.56x45mm NATO.
Don’t worry, he brought the .50 cal BMG too.
