I'm waiting for my 17HM2 barrel to show up, I decided to give it a try. I hade a contender barrel in 17HMR and the accuracy wasn't what I hoped for but from what I've read the HM2 is more accurate and flatter shooting than the 22 match so we will see. I have a 4x leupold to start with to put on it and depending I may switch to a variable.
