2300fps in the 404 is easily doable. I get 2335fps from 84gn ADI 2209 (H4350) under a 400gn Woodleigh with great accuracy. I dont consider this load anywhere near the upper end but more than enough. Only just above the RWS load that I comparison shot along with some Kynoch.

I believe the intent of the origional post was that with modern powders and bullets the 10.75x68 was able to be safely loaded to the initial 404 Jeffery loads, ie 400gn bullet at 2125fps and loaded as such would be suitable for the same game as the 404 was always suited to. While this is undoubtably true, it certainly could not be loaded to achieve what the 404J can now be safely loaded to.
