That's roughly the same muzzle energy as a 6 round burst from a 9mm submachinegun Love the shot that ended up on the roof

The power potential is clearly there, when are you going to try some sub-calibre saboted rounds?

[jagerbond]

Most of the materials are at the shop. I've got a big box of used carbide endmills too. Testing and high end stuff can ensue... Especially now that the manufacturing is finished for the 1.7, 2.0 and 2.5.

We've been trying to buy a plastic injection machine of the west coast to offer a cost effective way to handle the sub caliber stuff. 2 machines we have committed to purchase have fallen or tipped over while attempting to load them. We are asking ourselves "what are the chances?".

I got to get a forklift ride to the roof.

That was impressive as he11!

I watched that video many times.
The projectile appears to be quite stable.
Any longer range shots planned?

Looking forward to see what you can come up with, piercing that 1/8" plate is certainly technically possible with the right ammunition

...piercing that 1/8" plate is certainly technically possible with the right ammunition.

Easily so, given I think it's possible to get through 1/2" steel with a muzzle energy of a little over 300 ft-lbf - and not just with a pinpoint hole either.
It would take the right projectile, but the numbers suggest that it's feasible.

With over 2000+ ft-lbf on tap, 1/8" steel shouldn't be too much of a chore.

Wow amazing dude! That is some massive recoil and like people said they seem to be very stable in flight!
I've seen other advanced spudgun videos on youtube and many of them had trouble going threw a tv screen at POINT BLANK... you did it at like 20 yards? HOLY nice job man...

You made a beast of a cannon :p

Boom,

The videos really don't do the things justice. The anodized parts on the newer units push them over the top. They always had power, now the new rounds make them shoot like true guns, not overgrown pop guns. Too bad they are so much work and hence somewhat expensive. Mike has more new product under development to reduce prices for our budget minded customers. BTW, that was 30 yards....

Does anybody know the construction of these so that I make some of my own

[jagerbond]

UHMW tail assembly, steel domed cap. We're using a socket head cap screw to fasten the cap to tail assembly. If your creating your own, you'll need to pay close attention to the CP and CG differential. You will need at least 1/2 caliber difference. Our design you see here is a result of many revisions and our criteria was to make as short as possible (lowering drag, conserving material and keeping the cost down), with 1/2 caliber CP / CG differential.

compound spuds are exellent!!
they are highly durable compaired to most ammo
and they are balanced (potato is not), have a sealing ring
which makes them able to hit harder and fly further than most things

[jackssmirkingrevenge]

compound spuds are excellent!

We've noticed posting some pictures and/or videos of your personal experience with these rounds is always appreciated though.

Watermelon shot. Now you see it...Now you don't
