through my hunter elite now and I have to say that at one time I thought my gun wasn't up to par on shooting good groups but after the last 100 pellets or so I am starting to shoot good tight groups, at least for me. Thanks for all the info that you guys share on here. I am kinda quiet because I don't know alot about air guns..yet! but I will get there. I am really pleased with my rifle now. The GRT-III has helped a ton! Thanks again! Will report back soon.
