Aluminum gas checks

[sirgknight]

have any of you used these? i've read about some concerns of aluminum oxidation and the thickness of some materials used, but I'm primarily concerned with a snug fit with boolit. I've seen evidence where there is little to no loss of accuracy, but I'm up for your opinions.
