300 Win Mag 168gr loads

[fobb]

Just bought a 300 Win Mag Sendero and want to reload ( prices are horrible now) I have quite a few Sierra 168 gr. HP Match bullets and I am wondering if anyone has any pet loads. I will be target shooting out to 400yards.
Thank you

Don't write me off because I'm talking about loading for my 308 Norma Mag instead of a 300 Win Mag - one is almost identical to the other ballistically. Besides, I did a lot of loading for the two 300 Win Mags I used to have.
Anyway, my favorite all-around big game hunting load for my 308 Norma Mag is a Sierra 165gr HPBT over a large (near listed maximum) charge of H4831 powder and a CCI LRM primer. I tried RL-22 powder in all of my .30 caliber magnums too, but I like good ol' H4831 the best.
