Sir Larry,

Does your Swedish 350-gr CPS looks like the old ones from Wyoming ?
First picture is from an old MidwayUSA ad where they no longer stock the bullet.





The elephant leg test (below) is a tough test medium, into bottom of feet and into leg bones and other tough tissues,
longitudinally up the leg.
Similar results to Doc M's test at MIB Laboratories (above).
BTW, the elephant legs are on dead elephants. Live ones won't stay still for the testing.



With the 350-gr TSX loaded to 3.440" COL in the .458 WM+, following in Sir Bob's footsteps,
I used 81.0 grains of H4198 in Hornady brass with F215 primer
to get 2806 fps MV from a 25"-long Shilen barrel on a CZ 550 Magnum named Bobbarrella.
That was 2788 fps at 5 yards, correcting for BC = 0.271.
3 bullet holes touching at 50 yards.

Prior to that, 72.0 grains of H4198 with 350-gr Hornady RNSN at COL of 3.165"
(W-W brass, F215 primer)
gave 2526 fps MV from a 24-7/8"-long CZ barrel on a Pre-'64 M70
named Chimera WinCZechster.

I bet the 350-grain CPS would do very well at 2500 to 2800 fps in a .458 WM.
Probably as accurate as any 350-grain bullet to be found.
