I am terribly sorry to have to make a separate thread for this, but i have spent almost 45 minutes searching with no luck.
A week or so ago (i think... i could be completely mistaken) there was a cannon posted that was powered by a 12g powerlet. I do not remember the posters name. I believe it was some sort of paintball/airsoft morter, but thats not the part i am interested in. The thing that stuck out was the firing mechanism. It was some sort of pin that punctured the 12g, thus pressurizing a chamber until the burst disc was ruptured.
The reason for finding this cannon is that i am in the process of designing a copper QEV dart gun/sniper of sorts. 12g would be a nice way to power, especially if i can use them a ammo as well... but this doesn't need to be in this post.
Any how... if any one could point me towards that cannon, it would be much appreciated.
