I just did a quick GGDT on the SWAT, and even with a 3" porting burst disk valve, with a 100'x3" barrel, on a very hot day and a low friction projectile, using 150 psi, it couldn't exceed 600 fps. With the 3"x20' barrel that you have, the maximum velocity you could expect with the SWAT firing a 6 pound slug is about 380 fps, with very favourable inputs. Probably more like 350.

ok. I think i got it confused /w/ the 1.5 pound slug. well, even then, 350 fps could do smoe damage. also, the barrel was 2" aluminum.


here's some vids.

I counted. 6 sheets of 16th inch steel, and one sheet of 1/4 inch aluminum. killed @ 45-50 psi.

. the videos are long, and may take a little bit to upload
the ones with arrows are the good ones, although I recommend them all :wink:

here's the oven the night before the shooting

the first three show it's accuracy. they hit in the exact same spot.

this is a 30 psi shot /w/ 1.5 pounder

another 30 psi shot /w/ 1.5 pounder
http://media.putfile.com/oven-3

another one punches a hole in the oven (30 psi)

:arrow: a 40 psi shot (the talking may sound like nonsense, but me and my friend cal were having a conversation, so that's what you hear :oops: ) THIS TAKES A WHILE TO UPLOAD. be patient, It's worth it.

:arrow: here's as I said in the vid, the best video so far :oops:
http://media.putfile.com/oven-77

:arrow: here's the 6 pound slug at 35 psi. had it hit front forwards instead of on the broad side of the slug, It would have gone straight through. notice the corner that hit first still left a pretty big of a hole.

:arrow: :arrow: this time, the 6 pound slug hit the latch mechanism ( jammed after the first couple shots destroyed the opening mechanism) anyway, It went through the crack, tore through the plumbing, electronics, steel, and insulation, then out the back.
