300 Win Mag help

[saleen63]

Does anybody have load data for 180 gr nosler accubond using h4831sc in a sendero? I called nosler and the guy I talked to seemed like he had never heard of this powder. Kinda strange. I see a lot of people are using RL-22 for this bullet so if this the best for it then I will use that. I have searched for the load and posted this ? in the reloading post for 300 wim mag with no results.
Thanks for your help.

I load H4831SC in a 300 Weatherby Mag. using 168 gr. Berger VLDs and also in a 300 Winchester Mag. using 200 gr. Accubonds with excellent results. I know I tried RL-22 in the 300 Win. Mag. and also tried lighter bullets but those loads didn't do as well.

Just find data for any 180 gr. jacketed bullet with H4831SC and use that as a starting point. H4831SC is identical ballistically to H4831 so you can use H4831 data as well.

Re: 300 Win Mag help

I tried several powders in two different 300 WM's. With the 180 gr. Nosler Ballistic Tips and Barnes TSX's IMR 4350 gave me the best accuracy.
With the 208 & 210 gr. bullets RL-22 worked best.
Hope this helps.
