Looking for load information 300 win mag h4831 180 grain Partition. Thanks

Suggest IMR 4831 @ 74.0
180 AccuBond 3.390”
WW brass and WLR primer ( not magnum)
200gr AccuBond with 74.0 H4831
Same brass and primer I reserve H4831 for 200gr in the 300 win mag.
IMR 4350 with 150/165 and Reloader 22 for 190gr.
300 Win Mag one of my favorite rifles to load and hunt with. The 300 Win Mag like the 30-06 will always be part of my arsenal ! Today I prefer IMR 4831 and WLR not magnums primers in WW cases with 180gr AccuBond this is a real 300 Win Mag load not watered down ! This load is very similar to the great Finn Aagaard load of yesteryear!

Years ago used 78.0 H4831 with 180 Nosler Part and 76.0 with 200gr Nosler Part both with WLR primers in WW cases these are top vel loads and extremely accurate in Win 70 I had at the time.
