yup if you cant kill deer at 300 yards with 9x its time to go to the eye doctor or take that blister pack tasco off and buy a good scope. One of the longest shots ive made on a deer was 524 with a yards according to my range finder. Gun was my 7stw. Deer dropped at the shot and my buddy asked where my scope was set for a long shot like that. I looked and it was set on 5x. Sure didn't look in the scope and think that I needed to turn it up. thought never crossed my mind. I usually leave them all on 6x figuring if I need more I can turn them up but other then just playing around and trying higher power leave them right there. Don't even know how that one got down to 5x.
