That's extra gentle, even compared to the loads in the Lyman cast bullet handbook. I'm guessing 14-15 grains Unique if that for the load mentioned.I can't remember the load but the guy who got me into the 458wm loaded his browning safari with a 500gr cast bullet over unique and creme of wheat for 900fps. That was his practice load before going to Africa.
He said he fired over a thousand rounds to get used to working the bolt. He took 46 animals including elephant. I actually have the bullet that took his elephant.Most of the cast bullet loads are near full velocity loads. If I was going to practice before going somewhere with animals that could potentially kill me id rather use something near a full power load so I know what to expect.
Theirs some data for 5744 issue is finding 5744I used AA5744 when I was playing with cast in my 450-400NE, I'd bet Hodgdon/Western/Accurate has AA5744 loads for the 458. At the time, about 2012, I just e-mailed them and he sent me all the unpublished data he had on the 450-400.
Your friend did a good job learning that rifle with reduced recoil loads. Repetition builds muscle memory. When you're hunting and are presented with a shot, the rifle seems like it mounts, sights, and fires on autopilot.He said he fired over a thousand rounds to get used to working the bolt.

He shot skeet with a 410 and always said it was like shooting a running buffalo. He shot extremely well in his day.
