swift scope problem
OK .... I was out shooting my pro hunter yesterday .270 , topped with a swift 3x9x40.First two shots touching perfect... next shot dropping 6 inches and then again 7 inches and left. Scope seemed blurry.Adjusted magnification from 3 to 5 clear again ...shooting same place low and left .Adjusted and fired .. could not see a damn thing scope was blurry again .Messed with focus could not clear.Adjusted magnification and blurry at 3x clear at 5x blurry at 9x.Mind you i checked all set screws and mounting bolts all is tight. Shot this scope on this rifle last year burning 4 boxes of ammo with no problem .Now i have had this scope for almost 20 years used it on .54 ml 30/06 pump gun.. never had a problem until now .As I recall this scope had a lifetime warranty... anybody have a problem like this .I have popped cross-hares ,had glass fog but never focus issues.
