I personally know a lady that has taken the following with a 20" full stocked Steyr 7x57:
Her husband developed the following loads for her:
For Elk, Moose, Bear, Lion: 160 Grand Slam/ 56grs Norma MRP/ Win Brass/ Win Primer (2797fps)
That load looks like it could get a might warm ... Not sayin ... I'm just sayin ...
GE
Could be, don't know. Does seem a bit fast, but then I haven't yet loaded any 7x57, or worked with Norma MRP. Just relaying what the lady wrote in her book.
