I have two Lone Peak Ti's in and one Pierce Ti and just finished a couple other Lone Peak and Pierce. The Lone Peak with nitride bolt runs smooth with no gummy feel the Pierce is gummy unless I Cerakote the action body then they get smooth, I've probably Cerakoted a dozen or more of them and it makes a big difference.
The Pierce can be had with a Ti bolt as well which make it scary, ridiculously light! Both actions are timed very well with the Lone Peak actually being a little better with no cock on close and little over cock. There may be another Ti action coming on line with a different coating that could be very interesting but for now, over all if I was building myself a Ti action gun right now I'd be running a Lone Peak Ti with Nitride bolt and Hawkins rings. This combo in a Manners MSC with mini chassis and fluted bartlien 3B at 25 inches plus brake and a 24 oz optic will put you just over 9 lbs hunting, you can drop a pound on the stock with ease. Same action and rings but in a Manners EH3 ADL with Swaro optic #3 Brux fluted at 21 inches will put you just over 7 lbs ready to go.
