Admit I'm a pellet fanboy but crows no longer come closer than 130 yards to my property, so needed something that carried energy farther and bucked wind better. Started with ZANS .30 slug assortment box, 6 grain sizes from 45.5 to 68 and ZANS .303 in .51 and 61 grain. Both V3 and U2 preferred 54 and 59 grains, neither cared for .303s. The famous AVS .3063 (61 grains) shot perfectly in V3, uncomfortable with extreme loading effort and costs, so set them aside. NSA 61.5 grain and AVS .3003 (60 grain) shot well but costs are high, .23 and .28 per slug, to-my-door, respectively. Purchased 4 boxes ZAN (59 grains) from Pyramyd Air, 11% discount and, "Buy 4, get one free," ended up @ .13 per slug. Keep a full mag, less one in chamber, of NSA 61.5s, in U2, one after another in same hole @ 50 yards makes me care less about the .23 and more about seeing another crow. WM
