I finally did some serious bench rest shooting with my new Gamo Whisper. I used a Caldwell "Rock" rifle rest and a sand bag for the rear of the rifle. All shooting was at 20 yards. The most accurate pellet used was the Crossman Premier hollow point, 5 shot group of 1 inch. The next most accurate was the Beeman Model 1222 gold coat hollow point, 5 shot group on 1.5 inches. The next two pellet types were at 3 inches, RWS pointed and Crossman pointed. Pellet brand and type does make a big difference in my rifle. It came with a Gamo 3-9X scope which i used on 4X. FWIIW
I have some varmints on my hit list, Their days are numbered.
