Just for curiosity's sake I bought some munimula (as per Ruff n Reddy that's Aluminum spelled backwards) PB checks from Sage's and was/am surprised these thin aluminum checks cost more than standard thickness copper ($28 vs $25 per 1K). It's not a big deal but I am having difficulty getting my head around the price difference being back-ackwards to the cost of the parent metals. The only justification I can come up with for the pricing disparity is the labor/difficulty of counting out those light weight checks. LOL
An aside, I am quite surprised how well these aluminum checks look installed. I haven't had the chance to fire some yet, but dang they look good prior to loading. Thinking seriously of getting some for my 44 mags.
