Wrought Iron Rounds? | Firearms Talk
Wrought (which, BTW, is the past tense of work) iron is too hard to be fired thru a rifled firearm. Rifling (usually in the form of light, spiral grooves engraved on the inside of the barrel) require that they squeeze and grip a bullet, spinning in, and markedly improving it's accuracy. In the EARLY days of back powder firearms, the smoothbore ...
