Recently purchased a Hatsan Flashpup QE as my first gun of any type (second if you count my red ryder). After spending a little bit of time with it and trying about 5 different pellets of varying weight and design I'm frustrated that I am at best getting groupings of about 2-3 inches at only 20 yards. I'm trying to figure out if the problem is me, my cheap scope, or the Flashpup. I'm using the gun with a bipod on the ground to maximize stability and the scope is a Winchester by Daisy Outdoor Products 4 x 32 AO. I purchased the flashpup from Midway usa on sale for $337.49 and am reluctant to return it considering the price I got it for. Any advice would be greatly appreciated as I am totally new to this.
