If it only shoots from a bench then in my opinion they should be fine. For a general hunting rifle, in my opinion, that is too light. I don't shoot prairie dogs here in GA, so I am talking pigs, bear, deer, coyote, and a trigger pull that light doesn't make a difference but does affect safety.
2# or more for me on any hunting rifle. Hunting ain't benchrest.
Also, I agree with the other poster, good trigger is more important that a light trigger. A crisp 5# is better than a crappy 2.5# pull.
I would also add, that at that weight, it makes a difference who did the trigger work, and the type of trigger it is. Did they know what they were doing? Or is it Bubba that read on the interwebs that light triggers are more accurate and and that any hunting rifle needs to shoot a one hole group?
