Odd that there's such a disparity between the Hornady calculator and the book. Unless I was setting the figure into the online calculator wrongly.
Average range of a 9mm and .357

Well, considering the 125gr .357 Magnum is a proven man stopper we should use that bullet weight in the "test" along with the same weight 9mm bullet. (well, at least a 124gr bullet)
I'm sure the 125gr .357 Magnum easily makes it across but not the 9mm. (too lazy to enter the numbers lol)

OK, again from Forker's book...
Hornady 124 gr. jhp/xtp, velocity at the muzzle 1110 fps and energy of 345 ft. pds. Bullet drop at 200 yards of 68.6", velocity at 200 of 881 fps and energy of 204 ft pds.
Look at a hot Cor-Bon 125 +P 9mm we see velocity of 1250 and energy of 434 ft pds. at the muzzle at 200 yards a drop of 59.7". Velocity falls at 200 yards to 893 fps and energy to 221 ft. pds.

Yep, and not all of it made sense for the items that had options so likely it was me.

What kind of .357 Magnum is that?? It's bullet is traveling slower than a 9mm?? Sorry but I have to disagree with your numbers. Why would you pick a very slow magnum round and a +P 9mm round. That bends the results in so many ways... I have shot .38 Special +P ammo that has almost that much velocity.
Why not be fair and at least use the .357 Magnum ammo from Cor-Bon in your calculations instead of finding the slowest .357 Magnum ammo you can.
Caliber: .357 Magnum
Bullet Wt.: 125gr CORBON Self-Defense JHP
Velocity: 1400fps
Energy: 544ftlbs

OK so here are two 125 gr. .357 magnum rounds to compare to the two 9mm rounds I gave above. I'm not sure what any of this tells us about the pond as most service or hunting calibers would make it across without a problem.
The figures I'm citing are taken from Bob Forker's book "Ammo and Ballistics" and are different from those you will get from the Hornady calculator because they are for simple bullet drop from a gun without elevation and without atmosphere or the sights taken into consideration. The velocity and energy are standard.
Federal 125 gr. Hi-Shok jhp 1440 fps at the muzzle with 544 ft. pds. of energy. At 200 yards the drop will be 49.5" velocity will be 937 and energy will be 244 ft. pds.
Speer GDHP 1450 fps with 583 ft. pds. of energy will drop 47.7" at 200 yards. The velocity will drop to 952 and energy to 252 ft. pds.
