what's the budget? I have a Swaro z6 3-18x50, has the 4w reticle, which is basically a duplex with windage hashmarks.....also has the ballistic turret and ballistic turret flex, which sells separately....it's set up for my smokeless muzz, but includes everything to adjust and tailor to your caliber specs.
I used it one season, and made the mistake of looking through the Z8i and now I'm bound and determined to raise the funds to buy one for this muzzleloader.
