Last year the Savage model 42 reintroduced the break-open combo gun to the company’s line up. It was a .22 LR and .410 combination gun. For 2013, Savage brought out a new version of the model 42 chambered in .22 WMR and .410 bore.
Both versions of the model 42 break open at the receiver for chambering and extracting ammunition. The top chamber and barrel is for the rimfire round, while the lower chamber and barrel is for the shotshell. I should note that the .22 WMR, also known as .22 Magnum, is not capable of safely firing .22 LR ammunition.
