So I've been struggling with getting kills. I am about to toss this Gamo out the window. I've moved from pellet to another heavier pellet and switched scopes. I also started to practicing my artillery hold. Recently I ordered a a couple of tins of people having success with the Gamo I have, but i have not tested it from my yard yet. In the past Ill go and try to shoot an iguana from 20-35 yards and I can hear and see my shots sailing high. I would adjust but after about 5 shots I would get frustrated and go back to the backyard range. So this time this guy was hanging out my backyard. I fired 2 times and both way high. I then shot it 2 mills lower and I thought I missed because I heard the pellet hit the grass and the target was gone. I went to investigate and this guy was sleeping. Looks like he had a rough time in the past he was missing about 1/3rd of his tail.
