ok,it's not the bullet that does not have the rifiling, it's the gun that did'nt have the rifiling,,i'm going back and trying to read the posts it seems to me that the cal. was in question? 1 example "The Taurus Judge"is a pistol and has no rifiling.the round in question has a ring approx. in the center which is a dead giveaway that a cased round has,,,i'll have another example in a few,this is my oppinion and has no bearing on anyones decision for i am not a professional gun and or projectile analyst,i do know that a casing will leave a ring on the round,it was not shot out of a slug barrel,it is contorted so you can't get a measurement on it,so if it has no rifiling that rules out any firearm that does have !! the question about solid copper rounds,if he cuts it in half and submits a photo of it only then will i believe it is solid copper,it' may be copper jacketed lead which may lead him somewhere else,,,idk
