Anyone used a tripod for Precision Rifle? I've read about the RRS but can't drop that kinda money on a tripod right now. Any thoughts on the Predator Tactics Deadeye Tripod System? How would it compare to the Nightstalker or the Shadowtech Pig 0311? These are the three that I've narrowed my search down to at this point. Primarily will be used for hunting, however I'd like to be able to use at range, but not as important as being useful in the field. I'll hang up and listen...
