Last time we went shooting we had a case of Tannerite sitting on the tailgate and I was strolling across the fireroad with 2ARs and an SKS when a state cop pulls up. We thought that he was gonna flip us shit and tell us that we could no longer shoot at our favorite spot (since it has been bouldered off for along time now). He asks if we have anything "Illegal" and I said "nope, we are all good." He asks what kind of firearms we have and I said "lots of em: AR's, SKS's, Glocks, and too many others to remember." I then ask if we are ok to shoot here and he says yes, just clean up when your done. He then went on to pull out a map and show us two other spots that are good for shooting. I damned near asked this guy about the Tannerite, but I was too damned chicken to do it! We waited for about 1/2 hour after he left before unleashing them.....FUN stuff!
Have fun.
P.S. I am still concerned about the legality of this as the sound will surely attract attention. I ALWAYS carry a copy of SGN with the Tannerite ad when we go shooting just in case I need to show the law what I am shooting at.
