Shotshells seem to be made predominantly out of a main plastic casing and metal parts near the base. Why is this not done with rifle and pistol cartriges? Plastic is a maagnitude less expensive than brass.

Shot shells are filed with fast burning powders. Rifle cartridges are filled with slow burning powder. I have seen some plastic 223 rounds but I am not putting them in my rifle. Sorry Can you imagian trying to scrub out melted plastic from the working of a rifle. yah I ain't doing it.....

Don't some pistols use fast burning powder?

But would it not be possible to make a pistol with cappability to fire plastic ammunition designed specificaly for that gun in order to make the cost of ammunion for that gun much less than what it otherwise might have been?

I see your point. Thanks for the info.
