Being new to shooting, etc I think you'd be doing better than avaerage if you can hold 2" at 100 off the bench. I have seen many experiencedshooters who can't do repeatable 1.5" groups. I agree with BC's comments on what you hear on internet sites should be taken withsome salt!!
With some time and finding the right load(s) this can be bettered if prepared to put forth the effort to achieve the results. When i started hunting I can't honestly say Iheld a 2" gorup with consistency, though I still filled my tags. It seemed for me for the first years the paper target was to much pressure, plus the little dot was a lot smaller then the lungs

! Over time I developed my shooting skills and things are much different if i can't hold a repeatable 1"/100 group then its time to do some work.
