RUGER
I recently traded a rifle for a Ruger 38-40 single action revolver. Only problem is no one has heard of this caliber and ammuntion has to be special ordered. Any gun dealer can order it , but they,re surprised when they find this caliber in their supplier catalogs. I know nothing of this caliber and need any information that you might have such as power, distance, use of weapon and how long it's been made. Any help appreciated.
