My 300wsm shoots awesome with 62.5 gr H4350 and a 168 gr Nosler BT.
I also shot 63 gr H4350 with a 165 gr Hornady SST. Really tight groups.
My brothers Tikka T3 shoots 72.75 gr R19 with a 165 gr Nosler Partition.
My Dads Browning Xbolt, brothers Tikka, and my Sako A7 all preferred H4350.
I hope that helps.
