Look, I'll just put a rubber seal on the delrin piston anyway just in case. Since all the plugs will be epoxied in place it will be virtually impossible to disassemble so it's better to be safe than sorry. I'll upload my final design soon if I can find a rubber to rub out all the unnecessary lines.

Should I also put a bumper in just in case? Are you sure the piston or the cartridge wont get damaged when shot? I'm hoping the cartridge will last me 50 shots at least before it shows signs of wear or damage.

Once I'm done designing I'll start designing the rifle cartridge which will probably be the same as the shotgun cartridge but shorter and a smaller diameter barrel. After that will start designing the bolt action mechanism and lever action mechanism. After all, I have until Christmas to design.

Do you think I should build the lever action shotgun first or the bolt action? I cant decide lol

EDIT: Is it possible to get a 1000 psi Shock Pump? Or is 600 psi the maximum?

Pretty sure, Delrin is remarkably resistant to impact. Just make sure it's flat surface hitting flat surface.

Lever action is quite a complex undertaking, especially from a tube magazine. I would go for bolt action from a box magazine.

While a shock pump's gauge might go up to 600 psi, it doesn't mean you can't push it further - but for a small pump it will take a lot of effort.

Alright I'm gonna make a bolt action first but I'm not putting a magazine or clip in it. I'm not doing that because I'm lazy it's just I don't fancy magazines on Bolt action rifles. On the shotgun of course it will have a tube magazine.

You could even try for semi/full auto I don't know if the carts would have the cojones to do this:

I can easily test to see if it will work with semi auto. Once I've built the bolt action I can fire the gun with the bolt facing upwards away from the locked position. (Pull the bolt left, back, forward and then right but don't twist it right) This will test the bullet and if It is powerful enough it should push the bolt back. If it works then semi auto or full auto is certainly a possibility.

First I'll build the bolt action, If my bullets are capable I'll make a semi auto and after that I'll make the shotgun.

On a final note, does anyone know how much the bullet in a 22. LR weighs? I might machine out my bullets for the air rifle and make them the same weight as a 22. cal bullet or even the same size too.

36-38 grain usually but it can vary.

I think that would be a cool desigh, but it will require very high presure.

Maybe you shouldn't put the carriage before the horse just yet, if I were you, I'd make sure a had a couple fully functioning cartridges that meet all of the criteria before trying to make the gun to fire them. They probably won't work just like they should on paper, so It'd be better to have the physical cartridge in order to design a gun to fire it

I know but you see I wont be getting my machinery until Christmas so I have a month to plan and design all my cartridges and weapons. Of course I will built the cartridges before anything!
