My stolen 17 MACH IV was recovered, but due to weather exposure only the McMillan stock and Leupold Scope are in good shape. My gunsmith has already ordered the Remington 700 Action and has a Shillen barrel in 17 Rem. to go on it. I'm pretty sure I'm going to go with it -- just a lot less trouble not having to form brass, etc. I just wondered if anyone had some feedback on the 17 Rem vs. the Mach IV. It seems like it's only a tad hotter, but a lot less trouble.
