I'm looking for some info with this combo. I'm developing a load for a $ SAUM using 131 HH. Current load is ADG brass virgin, WLRP Magnum, 62.8 gr of H4831SC. I'm up to 3166 with no pressure signs. I feel I can go faster but perhaps this is not the right powder? I went through the whole HH load data available through hammer time and no load data x 131 Hh for 7 saum. Any help is appreciated.
 
Wished I could help ya but you're leaving a lot on the table. I know a 7RM will take it to 3,400 easily so will the 7wsm. fairly comparable. 7mm Max which basically is a 7mm SAUM AI will take that bullet to 3,500 using the same H4831SC. Keep pushing it. RL23, N560, H4350 will all do it.
 
Keep going until you hit pressure. You still have room. Barnes shows a max charge of 64.5 of H4831sc with a 140 bullet.
