Wow a 400gr at 2400fps. No one's ever done that. Should be a winner if anyone ever builds a rifle for a cartridge capable of that. Now we need to imagine an animal, maybe a big black bull-like aggressive creature with thick horns like a helmet that charges the hunter to use it on. Sweet!
I always thought the .416 Chatfield-Taylor was more of a 2100 to 2150 fps cartridge.
Ken Water's in July 1974, did an article in Handloader or Rifle magazine on the Ruger .416 Taylor.
He hit the magic 2,400fps quite easily using IMR4320 powder, same as John Whooters did in his custom .416Taylor, using the same powder.
In my hardcover Pet Loads from the late 70's, the data is on page #311. He hit 2,400fps even using IMR3031 as well as with IMR4320, 3 loads, 2,401fps, 2,447fps and 2,469fps - using 400gr. Colorado Round Nose bullets.(Later Barnes, seems to me)
With the 300gr. RN's, he got 2,680fps with IMR3031 and 2,711 with IMR4320.
All through the years, KEN has been known for fairly 'soft' data. I think this is true for many ctgs. but perhaps not in this case.
Ken's slowest load with the 400gr. is 4gr. under max using WW748 powder and is 2,101fps. Max with that powder gave him only 2,226fps.
The next slowest load uses IMR3031 and starts at 2,182fps, with it's max. load at 2,400fps.
His IMR4320 loads started at 2,355fps and went to 2,469fps.
The load Ken suggested for the heat of Africa, was the 2,401fps load, 2 gr. under the 2,447fps load of IMR4320, as noted above.
