I had my mind made up I was going to buy a Zeiss Conquest Rapid Z 600 scope to go on a new Tikka T3 270 Winchester. Since then I have seen a lot of people using turrets. I had a few questions. 1). If 600 yds was most likely the longest shot you would ever take, would it be better for the average guy to hunt with a drop compensating scope or a scope with turrets? 2). Is a Bushnell 4200 Elite scope high enough qualtiy to consider buying turrets? (I am assuming you can add turrets to an existing scope) 3). If I am able to add turrets to my current scope, what am I looking at spending? 4). On a scale of 1-10 how difficult is it to become moderately proficient at using turrets. Thanks for the advice in advance.
