"a lot of speculation going on. the most powerful is hands down the S&W.460 with the S&W .500 right behind it" ==Metalmessiah
On one of my favorite topics? No Metal, I am doing the math, no speculation. I let others do the informed speculation. Here are
Chuck Hawks choice comments on the S/W 460.
"The 460's COL is too long to permit the cartridge to be chambered in existing Colt, Freedom Arms, Ruger, and Taurus revolvers,
so its popularity is automatically limited to those consumers with memories so short that they are willing to do business with Smith & Wesson.
Forsaking all common sense, which would indicate the heaviest pistol bullets available in the caliber for such a large case, the basic factory
specifications call for a 200 grain bullet at a MV of 2330 fps and ME of 2400 ft. lbs. A 200 grain bullet in such a big case is just about the
poorest possible choice for what is, realistically, a moose and elk gun.
Fortunately, there are many heavier and more suitable hunting bullets from Hornady, Speer, Sierra, Nosler, and Barnes available to the reloader.
460 reloading information is basically impossible to come by at this writing, but Hodgdon data shows that the 454 Casull cartridge can launch a
300 grain bullet at about MV of over 1700 fps with a MAP of around 53,000 cup. I would estimate that the 460 Magnum could exceed that
velocity by about 100 fps. That would be the kind of load that makes sense when using the 460 Mag. for hunting the largest North American antlered
game." Quote of Chuck Hawks
Now the math
460 Factory spec 200 grain with a MV of 2330 fps gives ME of 2400 ft lbs. Taylor KO Value is 30. Now in the above quote from Chuck,
454 Casull 300 grain with MV of 1700 fps gives 1926 ft lbs. The Taylor KO Value is 33
So if you load the S/W 460 with 454 Casull rounds, they perform better for hunting. (They will fit and fire safely, by the way since the
460 is really a 454 Casull in a very slight case lengthening, with a price streach that is way beyond reasonable.)
Before you rush out and buy a very slightly lengthened 454 casull, here is a word of caution from SoldierTech
"A local sporting good store reported to SoldierTech that Smith & Wesson recommend having the barrels replaced by the factory for a
$100 fee after only 1200 to 1400 rounds. This is due to the high-pressure gas cutting into the back end of the barrel. If the gun owner
would ignore this problem, eventually the cylinder would also start to erode, causing all kinds of functionality problems. " == SoldierTech
My old FreedomArms 454 also had this problem BUT the FreedomArms folk were wise enough to machine a replaceable (screw in)
forcing cone in the barrel rear. When it shows wear, unscrew it and replace for a couple of bucks. Replacing the barrel is stupid gun
design. That reminds me, now quite a few folk have bragged about the Dessert Eagle 50 AE and the S/W 40 auto. I think you need
some cautionary safety facts about your favorites.
Maybe in another post, this is too long.
