Cartridges seem to be making me more excited than they should nowadays...
What's your opinion on this Jack? It's probably a bad idea but I was thinking about those old wax dueling pistols and I was wondering how a company could make one time use disposable cartridges to fire wax bullets (that would grip rifling) for fun against other players.
I came up with this:
CascadingBurstDiskCartridge.png (7.3 KiB) Viewed 102 times

So it's pretty weird but its just a cascading burst disk system (with permanently installed non-replaceable disks) but to make it sleek the second burst disk is shaped like a ring, with a thin tube used to fill the holding pressure before being capped with yet another burst disk which can be punctured by a firing pin to vent it and release the pressure from the main chamber.
GGDT looks promising too:

With only 300 fps it gets pretty fast velocities and has less muzzle energy than a paintball gun (if it's still too painful pressure can be lowered, decreasing it seems to drastically change velocity)

Ignoring the fact that the wax bullet pointing out would be easily deformed and the fact that most spudgunners couldn't really cheaply or easily manufacture them, do you think it could be a viable design for a company to mass produce to take advantage of the dying paintball market and growing milsim market?

In my experience, cartridges are a hard sell for the simulation market. Yes, they are awesome, but commercially, most customers shy away from them. They need to be individually filled, tend to be expensive per unit and are easily lost in the field.

The APS airsoft shotguns for example are about as real an experience you can get and indeed the shotgun itself is almost identical in design to the real thing, yet they are not and probably will never be as universally popular as devices using a gas reservoir for multiple shots.

For paintball the "Real Action Marker" series also failed to really take off, the shells are just another consumable to purchase which most players are looking to avoid.
