Sounds like you were shooting a L.A.S.E.R. That plinker of yours sure is powerful...

It's late, you can already hear my colleague moaning in the background after the shot - more *proper* damage pics to follow :P

As to the sound, I'm guessing it's mostly BBs impacting with the metal door hehe

Cheers :) not much to look at really, just 2 pieces of pipe epoxied together, but here you go.

Update 23/11: I haven't really fired it much, namely 'cause it's far too loud for the quite suburban residence we occupy. As such I decided it would be worth sacrificing some power to at least have something I can use, so I cut down the chamber to 20cm, giving a new C:B ratio of around 0.45:1. Will try it out tomorrow and see how it goes :)

Update, tried it out with the new 0.45:1 ratio and, well, still loud as *profanities* :roll: but hey, it works :)
