I've seen and used the Winchester 333 bulk-packs, but yesterday was the first time I'd seen these: May be old news to some, but I've been in 4 different Walmarts in the last week, and only one of them had these. Anyone tried these yet? I only bought a couple of the Win 333s before they disappeared, mostly for plinking, so I haven't done any rigorous testing or anything. Price was $15.97. .
