They are both outstanding actions. If you are going with a #3 contour barrel, it makes no sense to use the heavy BAT or RSR action.
RSR is not a "tactical action", just another Remingtom clone(round reciever). Think my RSR weighed 1lb 15oz with recoil lug.
The new Stiller Predators are not the same as the old ones.
What took so long?
the Stiller's in question are the Predator
Seems to be a trend on custom rifle forums.
The newer Stiller Predator are now on par with the RSR but they were not when I bought mine.
There still not.
