I tired the powerbelts 195gr. with 150gr pelts this weekend as well with not so good results... At 100 yards, it was better then 2" groups... I am trying to make this an accurate 200 yard gun. So 2" at 100 is not good enough for me. I also tried the Knight barnes sabots with about the same results... I just orderd The new Hornady SST I will post later this week the results of that.
