Loading System

Unread postAuthor: storm33229 » Wed Jan 10, 2007 5:49 pm

Are there any cartridge loading systems available? I'm using AA batteries for ammunition. I'm currently trying to design one right now and I have a pretty good idea of what I'm doing... at this point I'm just trying to make it look good.

You mean like a bolt or breach?

I'm not familiar with all the terms yet... so... what is bolt and what is breach?

I don’t understand what you want

Its not like you can go to home depot or some place and say “hey do you got any cartridge loading systems for pvc, “yeah there’s one right here for loading AAs into your plumbing”

If you have to think up this stuff up to fit your gun, we don’t give or, tell pre-made plans because that’s stupid, but if you need help with designing I’d love to help :) , but first do a quickie reaserch on gun parts

A bolt action works the same as a bolt action rifle. You pull the bolt back, load the gun, and push the bolt forward and lock it. When they say breach loading they're suggesting doing something like cam locks or a male adaptor on the barrel.

This is the general design for what I have so far:

i see what you mean
like a springfield rifle they used in wwi. Your better off trying to use a bottom loading cartrigde/magazine with a spring and bolt though, like modern weapons, so that another round doesnt fall in as you are shooting, but that design would also work you just might get complications

and my own pet peeve would be to make sure the bolt pushes forward then locks, intead of just forward, so air pressure isnt shooting it back in your face. and the bolt should be the same size as the battery.

Well, since only one battery could fall at a time, I could push it forward, lock it, leave it locked in a forward position, fire and start over. Thoughts?

It took me a few minutes to understand because this design is so unconventional. The direction of feeding (top or bottom) isn’t a problem at all; this thing has got to be single shot,
I see you are closing the chamber using the bolt to slide over the opening, save your self the trouble and create a barrel sleeve to close the chamber opening instead.

plus: the barrel thingy doesn't do anythingy :lol: I would leave it out since you can just hold the barrel, or keep only one for a vertical grip

I'm redesigning it. I'll post back when I have a new design.

why do you need a loading system? you would still need to pump it up each time, unless you used CO2

You don't release all the air at one time... so no, you don't keep re-pumping. You can probably get 1-3 shots off of one tank, and yeah.. I could switch to C02 and put a PSI Burst regulator on it.

And as for the bullet angle, not something I am really worried about :)

1-3 shots is VERY optimistic. If you squeeze and release the blowgun lever you can get one good shot and another little poof of air.
