IIRC, The only rifle cartridge with operating pressures as low as shotshells (12,000 psi) are .22 rimfires - since most older CF rifle cartridges are about 28,000psi, and modern CF's go to 50,00 + psi.

Used single-barreled .410's can be readily found for less than $100, and are easily altered to your taste.
