I have done a bit of work developing loads in my std rem 260. I have settled on 120 Amax at 2990 Fps for hunting loads and 140 ELDM's for targets due to the less wind effect factor.... just guessing but the 140's are probably doing 2750 ish working backwards from Strelok.
The shock factor with the 120's has been great

@Mathias and @R93 when burning 760 have you had any ignition issues ? and are you running large or small primers?
