I have heard of Cadet actions, both .22 Rimfire and .310 Cadet being rebarreled & chambered to everything from .22 mags. .22LR's to .17HMR's and CF's from .17AH, .17Ack. Bee, .22KHornet, .218Bee to rimless cases like .221 fireball, .17 MKIV, .222, .223 and .22(4?)X50mm, an done in .30/30 Ackley Improved Winchester. A spring loaded rimless extractor is used for rimless cases.

I have just finished a .22 Ackley Hornet on a BSA Cadet action.
