Well this last season was the best for long shooting of any of my hunting buddy and I. Last year we got 1 good buck at 477 Yds and 2 does at about the same. The year before was our first year to hunt racing goats and we took our first at 335 or so and then I got mine at 608. I got 1 at 1205 yds. One at about 557 yds. A couple with short range rigs for good measure. We want to come up with a better way to measure distance as our reading with the RF1200 seem to always come out long beyond the 700-800 yd mark. Does anyone know about the Vector IV or the Newcon 6000 yd model. Also about big eyes? Where can you buy'em at? Any help is great!!
