On a recent thread, someone said that it is possible to load 357 Magnum up to a point close to 30-30 levels (I'm using this as an example). Is there a measure or calculation that shows how and increase in diameter might make up (for lack of a better term) for a slower velocity?
Example, assuming similar firearms and ranges around 100 yards: a 160 grain 30-30 round with a muzzle velocity of 2200 fps is equivalent to a 158 grain 357 Mag. traveling at X velocity? I would figure that the 357 velocity would be lower, but, could still be equal to the 30-30 because the 357 punches a bigger hole.
Thoughts?
