SpudFiles

Now that the weather has warmed up a little bit, it seems I've caught spudgun fever as I built this over the weekend out of spare parts because I felt like making something with a bolt action breech.
Basic 1" sprinkler valve cannon; 20mm chamber 110cm long, 15mm paintball barrel 110cm long. I've taken it up to 150PSI, might go higher, probably not. GGDT says about 750fps. Oh and it's bolt action

P.S - I had a bag of about 200 paintballs from two years ago that I've kept in a draw in my room and they were really soft and seem to have expanded so I chucked them in the freezer overnight and they're still too big for my barrel. I've used these paintballs with the same barrel before when I first bought them but now the paintballs wont fit.

Looks nice. I like the paint and the layout, it looks comfortable. Maybe the PBs don't fit because of the hose clamp on the breech. Can you muzzle load them?

I don't see what the hose clamp has to do with anything concerning the paintballs not fitting. Possibly the breech itself isn't wide enough for the paintballs to get through, but that would be an obvious and easily fixed error.

Na

I don't see what the hose clamp has to do with anything concerning the paintballs not fitting.

Since the hose clamp is so close to the end of the pipe it could compress it and make it smaller in diameter. The breech is well large enough, the paintballs just don't fit in the barrel, perhaps i'll bore out the end of the barrel.

pretty similar to a paintball cannon I built a couple years ago

I was actually looking at that the other day, wondering if I should go with a larger stock like you did.

where you don't want to risk over-penetrating a target and putting an APFSDS round through the side of someone's house.

I figure that if I ever get around to shooting this titanium bullet-shaped projectile my friend has, I'll go up the road to where I filmed my tennis ball gun stuff. There are huge gun magazines which will make a nice backstop

that look really good MrCrowley i like it's layout but i don't know y you have that valve on the intake.

Valve on the intake? Do you mean the ball valve on the quick connect?

That is a male quick connect fitting. They have no check valve nor no valve at all, so he needs to use the ball valve in order for the air not to leak out when he diconnects the air source, most likely a compressor.

oops i am such a n00b
