(Maybe this should go in tactics & training, but because it's distinguishing between rounds, I'm asking here.) I picked one of these up to practice with in my BIG back yard, got it home, and read the warnings. I can understand the reasoning behind most being that bullets ricochet off metal, but.... -Why is .38 to .44 OK and .22 not? -Why minimum distance of 25 yards? I'd like to start at 10 yards. Is this just a case of mfr. CY* or are ricochet injuries a lot more likely if these warnings are violated?
