I have a RimX action up. Most don't want to pay extra for a $1600 chassis, and a $4000 scope, on top of the action, so only listed as a barreled action with mags. Plus this way you get to choose your favorite stock, and trigger, and glass to make it yours!
I'm over $3000 before taxes into the barreled action. At this rate, I might just hold onto it and make it a 17wsm.
Such an easy swap to 22 mag, 17 mach2, or 17hmr for the rimX. Replace prefit barrel, new bolt head, and new mags gets you into a new caliber. Same action and main bolt body, and all will work with the rest of your system. The 17 wsm requires a new complete bolt, new mags, and new barrel. I'm really surprised at the lack of people playing with this option.
