I shot some 1918 30-06 not long ago .... use to shoot some pre-WWII 45acp when it was available!!
Many, many years ago I gave my father an S&W M-19, a box of factory .357 and some of my .38Spec reloads. When he died, my mother gave me the gun along with the ammo. Seems he had only shot about 1/2 of the box of factory .357 and a few of the .38 reloads. I took the ammo out and shot it up .... not a single FTF with either the factory or my reloads after more than 25years.
If it is factory ammo - inspect it and if good to go, shoot it. If they are reloads - NO NOT SHOOT IT regardless of age!! My standing advise is to NEVER shoot reloads of unknown orgin!!!!!!!!!!!!!!!!
