the 45-70 case is quite a bit larger in diameter then the .45LC. it'll wobble around and not position properlyFirstFreedom said:Tangent question: is it safe to shoot .45 colt in a .45-70? I know it's not a good idea b/c accuracy will suffer, due to .451 vs. .458 bore. But is it safe? I've always wondered why it's not an issue when the bullet's edge hits the "shelf" or "lip" at the end of the chamber, where a non-bottlenecked cartridges headspaces - seems like in a worst case scenario, this would cause the bullet to yaw and therefore get stuck and therefore blow up and hurt you. Revolvers are different because there's a forcing cone. But how come this phenomenon doesn't happen in single shots or leverguns shooting .38/.357 or .44spl/.44 mag, etc., with wadcutter or semi-WC bullets? Seems dangerous.
