Tested 11 different slugs, from 3 manufacturers, in U2 and V3 .30 (700mm). AVS .3063 (61 grain) had high accuracy but discontinued use due to excessive loading force. Top 3, by far, in order of accuracy, NSA .300 (61.5 grain), ZANS .30 (59 grain), ZANS .30 (54 grain). NSA, with shipping, is .23 per slug, ZANS (59 grain) @ .13 per slug from PA with, "Buy 4, Get One free," and 11-14% discounts that show up around holidays. Future testing of additional brands, 59 to 62 grain range, would be beneficial, in meantime, keeping .30 magazines loaded with NSA (61.5 grain). WM
