ipaintball:Yes I know that it is common belief that ABS tears but that is not how it happened when my spray and pray went boom a year ago.
What happened to the spray'n'pray that went boom? Even my standard ABS barrel failing at a 500psi shock load just tore a 12" long strip off the side. Was there anything tapped into the chamber wall or fittings?
Spudfarm: DYI's barrel was solid core, like the chamber of this gun but unlike the potato barrel.
Yes, and the walls were also an inch thick. Very unlike your potato barrel.
Good little plinker you've got yourself there bigbob.

Well, this happened when I new nothing about spudding or anything else really. I had about 5 tapped holes in the single wall and it was cell core. The chamber kindof just blew into five chunks that went flying a couple feet. It wasnt a very energetic explosion, just some peices of abs and a loud noise.
