For anyone interested my 300 wby vanguard loves reloader22. I've been testing loads with 178 ELD-X. I tryed 7828,4198,H1000,7828 ssc and finaly reloader22. With 79 grains of reloader 22 i shot a .67 3 shot group then loaded 3 more and shot .73 3 shot group i'm happy with this. Also i loaded some 180 accubonds with reloader 22 starting at 79 then 79.5 and then max which is 80 grains. The 79 grain shot 2.7 then 79.5 shot 1.8 and 80 grain max shot 1.1
