I've bought the .177 Gamo 440 and shot a squirrel with true glo notched sights last month. I posted that hunt with photos in this forum. That was the day I received the air gun UPS. And, before I had the chance to mount the new Bushnell 4 - 12 x 40 sportsman scope and practice the required sighting in adjustments. Now I have the 2nd kill but this time with the scope on the rifle. As for wild life activity the past month I've seen 3 squirrels on my property moving briskly anywhere they want high, low, up and down except the all important spot down range of my best sniping window on the ground floor of my house. I can view due west in my yard and out to about 40 yards for a long shot if a bushy tail is perched sufficiently high in a tree. I can get ground shots on target out to at least 33 yards for part of the terrain. Here the woodland color is still grey/brown with a few redbuds but many spring songbirds, robins and bluebirds have been showing up and staying around. They are singing all day. It is a welcome feeling after the compared quite in the woodland in winter. The best part is that the neighbors are all inside for the season. There is a flock of crows that I can't quite figure out why I'd shoot one since to me they are not a nuisance. Friday was rainy 63 deg here and one wet grey squirrel was moving in the morning leafy slop along a hedge row. So I opened the window all day and had the air rifle on the shooting rest with RWS super HP ammo ready to hunt. At 5pm the Gamo 440 w/ scope and I had our chance. The rain had stopped mid afternoon and the sky's were patchy grey to black like tornado conditions but the wind was at high elevations not near the ground. I walked past the window and the squirrel was stopped scratching on the ground about 13 yards out. I knew this would be exciting and lifted the rifle, loaded the pellet, adjusted the lens ring to 12 yards, set the rifle in the rest, took aim. The squirrel moved. But as luck for me today would prove it jumped up on 18" high rotted oak stump at 15 yards and assumed the classic squirrel squat posture. It was profile view and looking to my right. Exactly the "Iron Squirrel on a rope" stance that Gamo sells for plinking. I settled the rifle in the rest and lightly on my shoulder,released the safety and took aim on his head at 7 x power. I pulled the GRTIII trigger straight back to the grip and let off a blazer at this close range. That squirrel took the hit, jumped forward off the stump while somersaulting 1 x backward. I have seen this reaction before and it is always an instant kill. Have a look at the two pics of this hunt, my second kill with this rifle, after a month of looking for a chance while basement sighting in to 10 yds, 20 yds. And breifly sighting out in my yard to 30 yards with Meisters, C HP, RWS Super HP and Gamo Hunter two tone pellets.
