Long time shooter off and on like most people I started off with a daisy BB gun, lived on a small farm so had plenty of opportunity to hunt most of it with a shotgun and my dog, graduated high school, soon realize all of the pleasures of being a kid were gone including my hunting as of late I acquired a Gamo swarm out of necessity I was having a severe rap problem and the rats are real smart I only caught two with traps and they persisted so I got a Gamo and after 2 weeks my rap problem was solved they were still there but they didn't visit my vicinity. I traded the Gamo for a mountain bike, that brief time of shooting with it my whistle and would like to continue. There's one thing I didn't understand when Steve mentioned he always senders his scope can somebody tell me what that technique means.
