This is an analog test of the NSA 400 grain hollow point fired from a Texan SS .457 PCP Air Gun at 50 yards. 5/8 plywood, gallon jug of water dyed red, and a 4"x6" backer. I wanted to see what the probablw affect of 400 grain slug would do to a deer sized animal. Doesn't prove much but the slo-mo is cool.
I also compared the enormous size of the .400 grain NSA to a 5.56 Nato round.
