I have a 6CM w. LP Fuzion TI. Bolt is Nitride finish. Action is smooth as silk.
I have another LP Fuzion TI on the way for a 6.5SS build. Full action Nitride finish.
I have shot a few others in .280AI, 7RM, 28 Nosler, and .300RUM. Never had sticky bolt lift in them until I hit pressures that any action would have sticky bolt lift during load development. Had similar results with the Mesa Crux I shot too. LP seemed slightly smoother to me, but not much. Full Nitiride is extremely slick though.
I have shot three Pierce TI actions with the TI bolts (one was Cerakoted, not Nitride, and two with Nitride bolts only) that had sticky bolts before I expected it. Personally, I think it is TI bolt and TI action that seems to exacerbate the issue.
Lone Peak and Mesa Crux uses TI action, steel bolt configuration.
