300SAUltraMagI have some good hunting load... What you want to do ? Hunting big game, target ???
For Hunt, I suggest the 200gr Accubond... Or the 180... But I prefer the 200... I'm able to shoot a 200gr at 2819 fps. I think it's the best bullet for this caliber.
I have some good receip but it's not perfect yet, but really good for hunt:
200gr Accubond
60gr IMR 4350
COL: 2.845 (Max COL for my Magazine)
Primer WLRM
Chrony at 2819,2821,2806:2815.33
Group 1" at 100 Yards
I have some tunning to do to this load, but for Moose Hunting, it's already good for me, It's only my second year in reloading...
I tried the same receip with CCI BR2 primer, speed was a little lower, 2786 FPS, but group seem to be better too, 0.5" at 100 Yards, with a COL of 2.825".
This is out a 22" barrel !!!

MyNameIsEarlHave had real good luck with IMR 4350 WLRM's and 180 grain partitions.
I've mainly loaded the 168 TSX and now TTSX in 2 of these. The 4350s, Varget, and Re19 work very well. However, H4895 is what my friend settled on for accuracy. We do not know velocity.
You can always reference the webpages for various powders and bullets and they all should have load data for your caliber. That is what I did.

300SAUltraMagIve found good load too with Barnes MRX 180gr.
H414 59,56gr.
CCI BR2 Primer
COL: 2.868 (Don't enter in the magazine, single shot)
Group @ 100 Yards: 0,437"
Chrony at 2873 FPS
But for the price, I prefer Accubond, only 54 FPS less with a 200gr. Bullet for les than twice the price...

YUMANI think it might be a little dificult to get 88 grains in that case.

Tony Rbarnes reloading manual says 88 to 93 grn of H4831. I started out low and have been very happy with the load. Killed a bull elk at 575 yrds last year..
