I also have the Savage black synthetic with the s/s bull barrel. I had originally bought the Bushnell Trophy 3-9x 40mm. I like the quality of the optics but thought it didn’t have enough magnification so I just got the Bushnell Trophy 6-18 x 40mm. I would find that going with a 4x scope would not take advantage on the accuracy of the 17 hrm for longer shots at small targets. That’s just my opinion.....
