I have a 1937 Rem. 341 "Sportmaster" and it's replacement, a 1942 Rem. 512 "Sportmaster". Both are excellent quality, very accurate rifles. They are from the old days when the steel was good and strong. I shoot modern .22LR ammo in both guns without any problems. The pressure developed in a .22 are not going to harm your classic rifle.
