Re: Pressure rating for Coaxial cannons

That is a really good question. I think it would hold / withstand greater pressure do to the fact there's no where for the pipe to go but into it's self. Sure it can collapse into the inside diameter of the pipe but getting the pipe wall to fold in like that...

Re: is my valve good?

Anytime you decrease a port size in the middle a pneumatic system, you create a choke point. It's best to match the port sizes or as close as you can.

Re: Canada prohibits spudguns over 20mm

So it looks like my 20mmplus bores are now prohibited!!! What do I do... get them grandfathered and so non-transferable? Do I get a compensation for turning them in? All my pneumatics are firearms in Canada (over 500fps) and I think any combustion would be too (combustion = fire). Not happy with th...

Re: Short question topic

@JRRDW, could you explain what you mean by air getting around the projectile and slowing it down? What I had in mind was a barrel diameter that narrows by less than a millimeter, going from decently airtight, to requiring a few tamps with a ramrod to fully seat. If the projectile is air tight from ...

Re: Short question topic

Okay heres a weird question that will probably be obvious in hindsight. I think it would make sense but lemme ask you guys: So obviously there is such a thing as too tight of a barrel for a given projectile. Unless you have a pretty massive air chamber, once you start having to hammer down a projec...
