Just FYI, the gun I was modeling was a 2" bore, 160x hybrid with a 48" long barrel, and a 38ci chamber. Note that I didn't say anything about it being light :roll:

Well, that's not exactly rifle-like, is it? :P
If you thought 4 bore was large, that's way past 1 bore - that's like 0.6 bore!!!

I know HEAL's .80" calibre is a bit on the generous side, even for an anti material rifle type of thing - but 2" is going a hair on the large side... :D
Does that thing kinda look like a big cat to you?

Well yeah, but to get 80KJ from a typical rifle bore barrel that long, you'd have to be loading the shells with CL-20 or something... :twisted:

Unposted guns? I have a few.

The newest hybrid version, a golfball gun, and a large combustion that is basically done, but just needs some minor touch-ups.

And probably a couple others that I forgot I had.

Nah. CL-20's burn characteristics are too damned hard to customize.

The only things I did not make are the 1.5" asco valves.

@ biged
I guess you can't judge someone on their post count! Bring on the badge system!
You can tell how awesome a cannon is by the pressure used.

I couldn't agree more. Post count is almost meangingless actually. It does signify some semblance of dedication to the hobby but that's about it. There are many avid (and knowledgable) spudders out there that don't bother hanging out online.

@Biged: Nice guns you've got there!

where did you find a QEV rated to 500+ psi?
