Yes, tried both, gave up on AVS .3063, despite solid accuracy, after having to use both feet to close sidelever! Ordered Zan's .30 slug assortment box and .303 in 61 and 51 grains. After several testing sessions, Vulcan 3 and Uragan 2 (700mm) preferred .300 (59 grains,) .303 (61 grain) coming in distant second. Of six boxed .30 Zan slug varieties, 59 grain was top, 54 grain next, followed by 49. Just ordered 4 boxes of Zans (59 grain) from Pyramyd Air using, "buy 3, get one free," and 11% midwinter sale discount. Also, ordered .30 slugs from two other vendors in 59-61 grain weights, to see if V3 might prefer. Uragan 2 loves the Zans 59 grain, V3 groups them better than the rest, would like to find a slug as accurate as AVS .3063, if possible. WM
