I am returning home Wednesday from the slope and have waiting for me, a BSA Majestic in 458 Win Mag, 150 rounds of new brass and 250 Hornady 500 grain RN bullets.

I have on hand RL7 and 10x, 4198, H322, H335, 3031, Trail Boss (for light loads), 2495, H4895 and probably a few others I'm not remembering.

I am looking for favorite loads with that bullet. I'll not be loading any other bullets at this time since I have so many of the 500's. I suspect the 2495 and 4895 will be too slow for it though they work well in my 400 Whelen. I am also not concerned with extracting every last fps from it. If a load is accurate and 2000 fps I'll be happy.

Thanks guys.

75 grains of H-335 is a wonderfully accurate load in my 458 Win Mag under the 500 grain Partition bullet, I use W-W brass and a Fed-215 primer, it runs 2155 fps from the 24" barrel on my old FN 458 WM Browning rifle.

IIRC Hodgdons website lists 1 grain more for the 500 grain bullets.

Thanks Jerry. H335 is high on my list to try. I thought I'd start around 71 and move up from there.

You're welcome Mart.

Best loads in my Winchester M-70 CRF 24" bbl.

H-335 75gr=2150fps
AC-2230 73.5gr=2186fps
Varget-74gr=2152fps
Win brass, Fed 215 primers, Speer 500gr AGS.

Average five shots across the screen @ 15' and corrected for velocity.
Elevation: 8200'
Temp: 85F
Wind: Lt/var
Sky: Scattered

First choice is AC 2230, then H-335, then Varget.

The AGS bullet is shorter than most of the other manufactured 500 grainers. Consequently, powder capacity as listed poses no problem in my rifle.

Best,
JLS

Both loads are extremely accurate, non compressed and valid in Texas August heat with no extraction issues.
