Save your money. I have one on my 17 but unless mine was/is a fluke, I wouldn't recommend them. Mine came with only one turret set...and it was for the 17 grain bullets. The first yardage marking on the turret is 100 yds. I was expecting it to start at 50 instead of 100. The Sweet 22 was awesome...came with turrets for several grain bullets and it went down to 50 yds. The 17 HMR only has 3 bullet grain weights available...seems like they could have made turrets for those 3 weights. That's the problem with mine...my gun likes the heavy bullets better...the 20 grn ones....and the turret ain't calibrated for that. I would have been better off just getting a high quality scope without target turrets and setting it like an ordinary scope.
