These look interesting. Cost appears to possibly be (from a just off the top of my head estimate comparing the .22 versions listed for both) about 50% higher than NSA slugs. Will be interesting to see how they compare head to head and see the actual cost when available but more options is usually good.
Could be. Glad I was one of "hoarders" who some complain about. I've got all I need right now. Not these fine specimens, obviously, but plenty of "others".
