All the better, it's easier to cut it off then add to it. 😁

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...

Re: Describe the ultimate potato cannon

I like this idea. I've yet to build a proper pneumatic. I actually like this idea a lot. It's simple yet has the benefit of the pump. When you say 2:1 you mean chamber to barrel ratio, correct? I would likely target a 200psi pressure for a pneumatic. I feel that should offer a reasonable and substa...
