I tried that for .22LR, and came up with one entry, CCI 22LR, 30 bucks for 100 rds.
[Folks here gave me a hard time for paying $80 for a brick (500rds). That's almost half price what ammoseek came up with.]
Other prices I checked were closer to normal. No .308mx, high prices on .444, deals on 30-30 seemed better...
This is a cool tool though, thanks for sharing.
Can't wait till things start to normalize, and then it'll come in real handy!
