Pritu: You are confusing the old .465 H&H Nitro Epress, 480 grain bullet @ 2125 fps with the modern (2002) .465 H&H Belted Magnum, the ballistics of which you are quoting. This cartridge is based on the .378/.460 Weatherby case, basically a belted .416 Rigby case.Pritu79 wrote:The .465 thats a caliber, propels a 480gr at 2375fps...that would be quite flat shooting for its weight.
As to the .240 Apex, the quoted ballistics were from a 28" barrel, as were most of the British ballistics. However, with modern powders the cartridge is capable of considerably better performance. It is an "unimproved" .240 Weatherby. The .240 Apex will chamber in the .240 Weatherby rifle, and will fireform to .240 Weatherby. Weatherby .240 cases can be easily reformed to .240 Apex. The .240 Weatherby is not a unique Weatherby developmen, but a "Weatherby-improved" .240 H&H Apex. Weatherby won't tell you that, but what a coincidence.
Cheers.
