Hey guys, So I know this is not the right forum, but I figured it is the closest to the topic of discussion. I have a gamo pellet gun (Big Cat 1200). It shoots 1200fps and is equipped with a 3x40mm gamo scope. It has worked perfect for over a year now and just recently (last 3 months?) has been shooting very inaccurately. At 25 yards, the shot groups are 1.5". Does anyone have any advice on how to properly clean/maintain a pellet gun or advice on a good kit I could purchase? I have used a bore snake but that was accidently thrown out. Also, is there anything special I have to add to the scope as far as mounting it is concerned..I have replaced it twice with no luck. Does anyone have any experience or knowledge they can enlighten me with??
