Went to the range this am. took the wmcs mine and my daughters. started out 15yds w/her .50 2 shots touching. moved to 50meters scattered them all over, mostly left 4" scope wouldn't adjust. Shot mine at 15yds, great group 6" right , that scope wouldn't adjust. tapped it, no change. Damn near threw the scopes in the creek!![:@][:@] Guess I'll clean'em up and try again! Glad I have a couple of back-up in lines. FRUSTRATED to say the least!!
