Hi Scott. Don't know about the .17 Mach2 NTX. From what I've learned, nobody I've talked to either on the web, or in person is happy with the current lead free .22 LR ammo..... The .22 RF Magnum apparently works well. I can tell you it shoots quite well in my Ruger Single Six. Been told it kills well too.
I kicked that meadow where you and I killed Grouse some time ago. Didn't get anything up. Decided not to hit my best spots. I've let myself go in the last year and am not really fit enough to go there. By next year, I'm going to be back at it. Hope and yours are well. R
