Reviving this old 7 STW load thread...
My favorite load for my Sako 75 in 7mm STW is,
Fed Brass, WLRM primers
79grs Re-22
140gr Barnes TSX, bullet seated 0.020" from the lands.
3396fps over my chrono, SD of 9 fps.
I worked up to this load and it is safe in my rifle. I'd recommend you do the same.
I've taken a Mt. Reedbuck, White Blesbok, Fallow Deer & a Springbok with this load. Performance has been stellar. From mostly DRT, to took a few steps and keeled over.
The White Blesbok was shot at almost 300 yds in a 25mph crosswind, with no compensation and the impact point was exactly what my last scope sight picture was. He took one step and dropped dead.
Typical 3 shot accuracy... well below 0.5moa
