The nutter was dispatched from a ground floor window to 18 yards out and upward to limb 11 feet high. I had to use the tru glow sights. The squirrel was sitting up on it's tail. She presented a clean sighting to the head (or heart). See the clean headshot. Trajectory is in the cheek, thru the brain and out just below the opposite side ear.... Amazing that this nutter still held on to the limb, hanging on by the front left paw and death shuttered for 6 seconds before falling to the ground. Squirrels are tough critters!. I got the my new $99 440 last Tuesday. Installed the GRTIII trigger blade and shot RWS super H point .177, .69 gr. pellets in my basement for about 35 shots to calibrate the Tru-Glow sights. Today at 11am this target presented herself and the 440 now has it's first kill. Fellow GTA forum members flagged a Bushnell Sportsman 4-12 x 40 gloss black $40 scope I also got form Natchez with the 440, both on deep on sale pricing. Timing, timing and thanks for the leads to "what I know will be a fun set-up". The 440 and scope are waiting for delivery of medium AccuShot 4 bolt rings to arrive tommorrow with some more ammo. Some of you may have noticed that the 850 carbine that I also have is now removed from the classifieds... I am keeping it for my first a DIY tuner project, I like the feel of that gun a lot as it is but with the tune I'll have fun bringing it up to optimum performance for it's standard energy class. I was in Bass Pro shop and see that the 850 carbine, same physical rifle, is now branded by GAMO as Nitro 17 model.
