I have both a LP Razor Ti and an AntiX. Both are nitride coated. I prefer the feel of the Razor Ti, it's a small but noticeable improvement in smoothness vs the AntiX. I do seem to show pressure signs slightly earlier then expected, but certainly within the normal variation of 2 different barrels. So it is tough to point the finger at the action, though I have heard the same as stated above. The Razor is close to twice the thickness of the AntiX, so while Ti may flex more, I'd be very surprised if the action, as a complete unit, flexes measurable more then the AntiX. If I was building another rifle tomorrow, I'm not sure which one I'd choose.
