Re: Some 3d printed ammo

Great stuff!

Yes it's my bought barrels that are oversize. The cpvc seems closer to paintball size.

Re: Some 3d printed ammo

I like it... would like the .68 too (although all my paintball barrels are much larger than .68)

Re: Finding copper pipe parts

IIRC some builders are sanding out the seam... I can't remember if I have done that but was going to when I get some time off, using a dowel and sandpaper. Slitting the business end of the dowel would allow shims to be inserted, sort of like old school rifling tools. Smaller pipe would also work ins...

Re: barrel thoughts

Found some stuff for Canadian residents. Small for low pressure pneumatics but possibly useful.

Re: barrel thoughts

So interesting! I was also considering modifying a current coax muzzleloader to have a longer barrel... if successful there is huge potential for adding rifling or choke or simply barrel length.

barrel thoughts

I've been thinking (uh oh) again about barrels. First, rifled chokes. I have a scrap .22 cal that maybe could be used as a rifled choke on the end of a smoothbore barrel. There is a hypothesis that a high speed slug slamming into the rifling might be bad for accuracy, but at pneumatic velocities pro...

Re: Pressure rating for Coaxial cannons

has anyone here tried a 10' muzzleloader? I whine about loading a 3'

Re: Valve jam with liquid gas

propane doesn't behave with some rubbers; might be swelling the o-rings

When we switched from acetylene to propane at work we had some torch heads and regulators get fussy

Re: Exhaust value with decent trigger feel

lift off valve, sear release:)

Trigger feel as you design the trigger-sear geometry

Also saves on a blow gun ( I am extremely cheap)
