Dump the 2400 and go to 296 with a Fed 155 primer. That gun will shoot if you keep the sights from moving. (GR: I have H-110 and planned to try that also, thanks)

Next you need hard lead and water dropped WW metal is OK, let them age a week before loading.
GR: Yes, did the water drop; what is the reason for the one week of "aging"?

It takes time for the lead to reach full hardness and boolits also expand a little. If you seat them too soon, the brass can size them a little under size. My .476" boolits actually expand to .478" after time. Still shoot great so I don't worry as long as loads chamber.
H-110 is fine, it is the same powder as 296 but might be a tad slower due to the lots Hodgdon gets. These days it might be the same though, I have not tested it lately.
Of all the deer revolvers I have, I love the .475 most. It kills fast, does not ruin meat and will work for any animal on earth.
You made a fine choice.
