Looking for input on my next air rifle. First is a brand-new Gamo Wildcat Whisper .177 with factory 4x32 scope for $110. Second is a used in excellent condition Gamo Bone Collector Bull Whisper .177 with an "upgraded trigger" and a 3-9x50 scope for $260. I'm leaning towards the Bone Collector. Decisions, decisions. All advice appreciated. Cheers.
