Caliber interchange question (CAUTION: NOOB!)
I've seen several posts here and on other forums about being able to use .38 ammo in a .357... Could someone educate me here, since I'm thinking that the number refers to the bullet diameter in inches (.380" and .357" respectively). If a barrel was .357" in inside diameter, technically a bullet that's .38" in diameter would be a EXTREMELY press-fit into a .357" hole. What gives? Please forgive the n00b question, but I'm trying to broaden my firearm knowledge!
