Loading Data for .458 Win Mag, 400 grain Swift A-Frame?

[cajunchefray]

Looking for reliable (manual based) data for reloading the Swift .458 400 grain A-Frame.

With the terribly unfortunately demise of Woodleigh, I'm seeking alternatives the their most excellent .458, 400 grain PP SN.

(What a terrible demise of a company,).
I don't know MR. Geoff Edwards, but can feel some of his pain, as we lost part of our farm in a fire in 1980.
I had developed a load (in only one attempt) with 74 grains Varget, and it regulated perfectly to the sights of my Whitworth .458 WM. Following Mr. Ray Atkinson's very logical advice, in that load a .458 WM, with 400 grain bullets, to equate with .404 Jeffery.

I have 150 rounds of Swifts .458 400 grain on the way, and knowing their reputation on game, I can work with that.

I don't have a Swift Manual., but load data in Pierre van der Walts book, "African Dangerous Game Cartridges", he lists Swifts data for use with Reloader 15, (unavailable here), Hodgdon- 4895 (I have).

I know these are "harder" bullets and am wondering if anyone has a " pet load" with Varget, H4198, or others.

I'm looking for 2250-2300fps, so not a max load.

Thanks
Charles

Altough they call it Swift SP, the A Frame is the only Soft Point made by Swift in that size/weight.

try @Badboymelvin on this forum. He does quite a bit of reloading on the 458 win mag and I am sure he can chip in with some useful info.
