That is the sealing face paiyaan the rest of the round does not touch the barrel, you just press them into the barrel, very snug fit. I only drill down the length of the ammo. I drill these on a milling machine.

OK, I gotcha. Looks like good stuff. The polyurethane that you use, is it the really hard kind, or is it a bit elastic? Not like I could use this on my 1 1/2" bore but I'm still curious, lol.

That's what I'm thinking, but I couldn't quite remember.

This is 90a duro, roughly as hard as bone.
I have made these up to 33mm dia so your gun would not be a prob
I also make some from 55a duro, just like rubber, BOING!!!

Hmm, what do you use for the tip on one that large?

Just a large sinker, they cost like 30 cents each though, so they get expensive real quick!

Casting would be a good idea becuase you could get a pointy shaped head, good idea Modder, VH man i don't know how accurate they are in airsoft cuz i'm in Australia, they should work just fine though,i put mine through mostly smooth Aluminium barrels, what barrels do airsoft use?

smoothbore brass/aluminum/stainless steel/ titanium. anything that can get smooth..............
im just thinking that i could possibly modify a classic airsoft style rifle to use these things in the magazines............... would hurt a little.......

No one has ever tried this in an airsoft gun before as far as I know. Maybe you could make a few of these and muzzle load them into the barrel of an airsoft sniper and see how they perform.

Just thought I would show you guys these as well, 33.7mm "Armour Piercing" rounds, The one on the left is Alloy base (hollow) with a high speed steel sharpened head.
The one on the right is Acetal base (hollow) with a stainless mid section, same head as the other one. I haven't fired the Alloy one yet, however the other one smashed a plate I made out of 3 sheets polycarb ("Bullet proof") Plastic 3mm thick each, in the middle was a plate of 12mm thick Acrylic then another 3 layers of polycarb. Dimentions were approx 10x10', all this was glued together with Acrafix.
It just plain smashed it into like 6 or 7 pieces, it was mad
