Well I did, for a little get the shoot this heavy thing. My first session was ok, I was hold that thing as tight I as I could because I first I wasn't getting any constancy by holding it loose. So when I was holding it tight I was getting great groups until I took a break for a little bit come back and I was still getting good groups but the POI moved a couple of inches. Anyways I was frustrated and put it back in the gun cabinet and left it there and 'til after I got back from camping for a few days. Well, I got back and I brought back to my shooting area and thought, "well I should probably try hold pretty loose and see how it does." And what do ya know, it was shooting dime size groups all day with Benjamin pellets at about about 16 yd. I am very happy and impressed with this rifle.
