Ballistically the 45 is equivalent to a 30 - 30. Those that say a 45 cal roundball for deer isn't sufficent, well let's say their experience doesn't match mine. The question will be the range you can shoot it accurately. I would comfortably shoot my 45 flinty to 75 yards with a roundball. The deer will have a double lung hole punched through it while everyone debates the effectiveness.
