I understand in Russia when 22 RF ammo was short or too expensive at some stage that some individuals reloaded spent 22 RF cases using a paste made from match heads to 'reline' the case heads, then a bit of powder probably black powder, capping off with a 22 cal BB or pellet and rotating the cartridge in the chamber to ensure an undented portion of the rim is presented to the firing pin.

Can't see why it wouldn't work, the Russkies may have to resort to this again if the current financials sanctions bite deep enough after their invasion of Ukraine.

Could be a way of reactivating cartridges for obsolete rimfires provided the owner has some spent cases or unfired ammo to start with i.e. don't through away spent rimfire cases!!!!
