Re: Do I need a canted base?
Do you "need" it? No. If you haven't used a ballistics calculator you may want to start using one. Like the one in the banner of each page on this site. Realize that if your scope were to zero at the exact center of your adjustments, it would leave you 50 moa up and down.
Depending on your intentions, a 6x may or may not be enough scope for your purposes. You will probably find that by the time you work yourself out to a 1000 yards you may wish you had more magnification.
But to say, "But you can't hit anything with a 6x scope at 1kyd anyway." is very dependent on the person.
