Testing a 12 gauge 1 oz Foster rifled slug (hollow base) in a ballistic gel format at a distance of 20 feet. Using SIM-TEST Ballistic Testing Media that has been recalibrated to match the properties of 10% ordinance gelatin. Brief review pre-shot followed by evaluation of the tested media. Test gun is the Mossberg 590A1 Special Purpose shotgun, 20" barrel.
With a muzzle velocity of 1600 fps, this 1 ounce (437.5 grains) piece of lead is packing 2484 ft lbs of energy at the muzzle. We could see a 50 lb block of gel go airborne!
