Thanks Clive; I like those slip top boxes. I hold the tops sorta-secure with heavy duty elastic bands.
There is a version for .45-70 (bullet-down), but the dividers were to low. I got the higher ones for belted mag cases and used a wood chisel to cut down the raised spacer-lugs in the lid to allow them to conform to the .45-70, etc., cases. Some I had to shorten the lid all the way around as well.
I haven't seen any around for years. Now I know where to get them.
