Well here I go again (not a scope problem). I thought I had this taylored load for this particular rifle and (I don't have a chrono) and come to find out I am about 300fps. slower than I had intended (borrowed a friends chrono). MagPro is too fast for this round. I am pushing the 142 SMK behind 58.0grs. of MagPro for 2670 fps.. My friend turned me onto this powder and it is accually quite accurate but c'mon, I need more FPS!!!! I guess I should tell you of the rifle to make a more educated response. It's a Sako 75 wearing a SS 26" tube, 8" twist. I need slower powder for more horsepower. Again thanks. /ubbthreads/images/graemlins/confused.gif
