This video explains the critical differences between .22 Long Rifle (.22LR) and .22 Magnum (.22 Mag) ammunition and why they are not interchangeable in firearm chambers. Firing .22LR in a .22 Mag cylinder leads to significant ballistic performance loss due to gas leakage and potential damage to the firearm's forcing cone. Conversely, .22 Mag rounds will not chamber in a .22LR cylinder due to their larger diameter. The presenter, TheYankeeMarshal, demonstrates these differences using a Ruger Single Six convertible.
