The Tasco world class 3x9 scope on my TC firehawk failed. This is the first scope problem I've had in over 40 years of hunting. The crosshairs have turned 90*. In all honesty this is the least expensive scope I've ever purchased. I guess it couldn't stand up to the pounding from the muzzleloader. I need a silver coated 3x9x40 to replace it with and after Christmas will begin looking at makes/models.
