I bought a Tac 30 from the group buy a couple years back. I ended up with a accurate as hell rifle (my first Brux tube at the time- not my last) but sold the gun not long later. The action has so little clearance that the bolt would bind if I breathed wrong during cycling. I think they're great for a bench gun, but unsuitable for the field. I'm back to tried Remmys for dirty work.
I have handled 3 of the predators and all portrayed the sticky,or binding bolt issues you describe, and I'm not sure it's because of tight tolerances, as Stiller is running as much as.006 bolt to raceway clearance, Bat runs .002-.0025 clearance on their bolts and I've never heard anyone say their bolts have binding issues maybe Cummins Cowboy will chime in, My Borden Timberline is smooth as glass and it runs clearances that are close to a Bat, not sure why they feel catchy!
