Not at all related to pressure, it just means it complies to this standard - so basically, your piece of pipe is safe to drink out of

i seriously think you are jesus.... Yes, my son, appropriate avatar don't you think :roll: I remember that well. It actually aided and abetted some of my cartridge loading ideas (You may well remember some of what I said in your thread). Yeah, had some time to spare so thought I'd repost some of th...

Slugs for a 3/4" barrel
Take an empty 12 gram CO2 capsule and saw it in half.
Put some lead in the nose, hold it in a pair of pliers and heat it up in a burner until it melts, then let it cool down and solidify.
Wrap some masking tape around the end or slip on the plastic part of a used 12 gauge shotgun cartridge.

Adapting 0.22 airgun pellets for airsoft barrels
It's pretty self explanatory, a couple of light hammer taps on the drill bit and you've got a good fitting heavy projectile that will still fly head first out of a smoothbore barrel due to the shuttlecock shape. If you can find 0.25 pellets, they'll fit in a 6mm barrel without modification.

I made it over the space of a week, what takes the longest is waiting the 24 hours the epoxy needs to cure. I was using 110 psi from my compressor (you can see the schrader filling attachment in the last video), never measured the muzzle velocity (I was using 0.22 airgun pellets flared out to fit a ...

Hey just wondering if anyone has any good ideas for rounds for a 20mm barrel anything mentioned here for a 3/4" barrel should fit pretty nicely in a 20mm barrel, try marbles and CO2 cartridges, and if there's a clay pigeon shooting range nearby you might want to see if you can scrounge any 12 gauge...

cartridge fed pneumatic prototype
edit: the concept has been revisited with much more success here . This was a prototype i made to test a concept of pneumatic cartridge feeding and ejection i had come up with back in glory days of spudtech :roll: I know it looks extremely ghetto but the intention wasn't for it to be pretty, it just...
