Ill have to call Duane Wiebe and see if that price line is close as thats the way to do it. Since caliber is already at 460 what would you go up to think as you cant make hole smaller! LOL! All of these are the 460 WBY necked up or shortened or ???
460 A SQUARE SHORT
465 HH MAG
475 A&M
495 A SQUARE=SHORTENED 460 CASE
500 WHISPER
.50 PEACEKEEPER
500 A SQUARE=The .500 A-Square is capable of achieving 8,127 ft·lbf (11,019 J) energy with a 600-grain (39 g) bullet launched at 2,470 ft/s (750 m/s).
505 BARNES SUPREME="the nominal bore size for that is .510? See P.O.Ackley's handbook volume2. It is the full length .460 necked up to .50. Single shot, unless you have a Weatherby or Magnum Mauser action. Full house smokeless loads in this caliber generate 10,000+ FPE. Best in a crew served weapon......."
Also found some gents talking about a 408-460 WBY!



but thats going the wrong direction to utilize that barrel.
Here is another bit of info: "The .460 Weatherby Magnum is the world's most powerful commercially available sporting cartridge. The .460 will launch a 500-grain (32 g) bullet at a chronographed velocity of 2,700 ft/s (820 m/s) from a 26-inch (660 mm) barrel, measuring 8,100 ft·lbf (11,000 J) of muzzle energy. Prior to the arrival of the .460 Weatherby Magnum on the hunting scene, the .600 Nitro Express had been considered to be the most powerful cartridge in terms of energy."
