The super-powerful air rifle thread was interesting, they certainly pack a wallop but the disadvantage is that you have to take time out to pump them up.
As another alternative to regular firearms, has anybody ever experimented with gas-operated guns?
I should imagine that a small amount of explosive gas let into the specially-designed breech from a small attached gas cylinder and sparked by a pull of the trigger would kick out a bullet at a fair muzz vel?
The advantage is that the bullet wouldn't need to be in a brass cartridge case containing powder because the exploding gas would propel it cleanly and efficiently.

You know, you could avoid the whole try to make a almost real gun and just Move to the US. They let us have the big boy toys here hehe.

All kidding aside, isn't what your trying to accomplish iffy over there?

Also what you just described sounds alot like a paint ball gun. I imaged if you subbed ball barrings for the paint balls they would be pretty dangers

The have already been expermental cartrides that don't have a case using solid propellant. Also cartrides that the whole cartridge was a rocket, Girojet.

Yes I remember the girojet it was supposed to be the next best thing in gun design then it just went away, I believe they never could get good accuracy. There have been some gains in caseless ammo but I think the major stopping point in military weapons is the case absorbs a large portion of the waste heat of firing. Ejecting this hot, empty case removes that heat from the weapon. With caseless rounds, other means of reducing waste heat are necessary, especially in automatic fire.

Accuracy was a problem with Girojet as well as the fact that it took some distance to reach effect velocity. You could stick your finger in the muzzle and stop the round. The round were also about 5 bucks back when 5 bucks would buy dinner for you and the wife.

I'm not planning on building a home-made gun myself, we Brits are too tough to need one and will survive by brains not brawn when SHTF..;)
If I really wanted a real gun I'd simply find a friendly farmer and slip him some cash to buy me a shotgun on his licence.
