1) That filing cabinet on the first page is an old government surplus cabinet from somewhere in the 40s to 60s. At the time, documents classified as "CONFIDENTIAL" were cleared for storage in such filing cabinets. In other words, they were considered "light" safes. Note that there are still a mess of those cabinets out there as they're so well made that they'll probably still be in use after I retire, but these days they're used as nothing more than simple filing cabinets and are no longer considered secure even more mere "CONFIDENTIAL" documents.
2) As the projectile clears the muzzle all that pressurized air suddenly has an escape path and it takes it. Result? Sudden tailwind on the projectile which can destablize it. It may very well regain stability, but probably not gonna happen in the 20 yards you advertise as your range to target. Taking a longer range shot may yield better results. Alternatively, a muzzle break may help by giving much of the air a place to escape that doesn't take it across the tailfin surfaces.
edit: Oh, and while your cannon is a beauty, I had to vote "I've made bigger out of spare parts" because... Well, Vera is made primarily out of spare parts.

Wow... this thread racked up alot of useless post's pretty quick lol, except for your's, Mr. Hall (which is why I guess I quoted it?).
Thanks for the tip! I really didn't put 2+2 together there and think of the effectiveness of a muzzle break on the fletchings of the ammo I've been shooting, makes perfect sense!
Also thanks for the head's up on the filing cabinet, it definitely makes sense and where it came from also points towards your suggestion. That thing was a beast! Very thick sheet metal, the thickest I've ever seen used on a filing cabinet, makes sense it was a confidential document safe lol. Also the lock and latching system was very overbuilt for any filing cabinet I've ever seen.
I'm uploading the damage shots video now guys! First video I've done on Premiere, gotta say I love the program now, it's very easy to whip up fast projects in. The video will be nothing more than a demonstration view... no steps where taken towards creating a cinematic masterpiece lol. Youtube's pretty slow tonight, so it prolly won't be posted till tomarrow (I'm uploading in higher quality).
Oh and Vera's a bit bigger... I'll give that to you lol.
::EDIT:: Damage Video finally posted!! it's still being processed on youtube so the quality sucks right now but should get better. The video is on the first page, second post of this thread.
