I’m thinking about doing a penetration test on some heavy curved plates someone gave me a few years ago. Bought a carrier vest to put them in, tried it on and was disabused of the notion I could move very far or fast wearing it. Bummed out to be truthful. Would a distance of 50 yards, rifle bullet calibers, 5.56, 7.62X39, .308 WIN, 30-06 SPR. Be a fair, valid test?
