I recently started varmint hunting last year. I shot a groundhog a 400 yds with a bushnell banner 4-12x40. I was wondering about the adjustments for elevations. Alot of people like the scopes with tall target turrets. Could I not dial in just as good with the regular fingertip ones? Whats the advantage of target turrets, are they just easier to dial in. The longest shot I have to shoot at is alsmost 600 yds. And I really aint wanting to buy me another scope right yet. Anybody have any comments.
