If you want one, you'll love it! Is there something more particular you're asking for input on? The RPR is the same across all the chamberings as far as how it feels and works. Are you asking about the chambering, the rifle, or...?
I've seen tons of RPRs on the line at NRL and PRS matches, and I've played around with one just a little. I even screwed a RPR barrel on a Hawkeye receiver.
