I just yesterday put out 8" diameter, ~3/8" wall high-carbon glycol pipe in 1, 2, and 3 foot lengths on the rural private-property range we shoot at, and they're GREAT! I got some of the spare ends that were left when they were putting in a new cooling system at the large office building I work at (yes, I asked-- the foreman was a shooter). We popped these things from 100 yards with .308 AP ammo out of a Savage Scout, and couldn't put a hole through it, unless the shot was dead-center facing you. 2"-3" to either side of dead center, it just spalled the metal. One guy came out yesterday and managed to put a very hot 100g 243 through the near wall, but you couldn't have gotten closer to the center without a compass, a protractor, a piece of line, and a transit.
Nice thing about the pipes, too-- they ring like bells! Absolutely NO question about a hit! At 250 yards, you hear it even MORE distinctly: "Ker-POW!......
Bong!"
We also got some hunks of 6" glycol pipe, possibly more suitable for 100 yards, and, of course, possessing a tinier center. In all, I put out 10 dingers, and the cost was zip. In many dozens of shots fired at them, only two holes thus far have found their way into any pipes, and all that is needed is to turn the pipe about 20 degrees, and the holes come out of play. The bullets, by the way, are recovered at the bottem of the pipe, having not even really peened the interor back wall of the pipe.
So, you might check with a welder or contractor who does such work, because a one-foot length of 8" pipe is pretty much worthless scrap to a crew hanging 1000'+ of pipe, but it could be golden to you...
