My youngest daughter killed her first wild pig with a Martini Cadet rechambered to .32-40. The factory-load 165gr bullets are too heavy/long/slow to stabilize with the .310 Cadet twist rate but resized 150gr 8mm projies did the job. Practice and safety training was all done with the 90gr Nambu pistol bullets from Taipan back in the day: bugger-all recoil and single-shot ejector is the perfect platform for kids and beginners.

Friend of mine uses a Martini Cadet that now wears a stainless .308 barrel from an early mini-thirty Ruger. It is chambered for .30-30 Win: fires and ejects Winchester factory-loads freely all day long!
