Re: Die Storage
I am not familiar with your exact dies but I have had dies that don't fit the factory box. My problem was diameter related and not length. I used my Dremel to remove material on the plastic supports in areas where they were too long or wrong shape.
If that won't work, try the clear plastic cases that are sold as inserts for soft sided tackle boxes. some have adjutstable dividers for length and width. Depth varies with type so take the die with you if shopping locally.
Also look at MTM ammo cases of ample size and cutting out cartridge dividers as appropriate.
Cigar boxes make good general storage too. If you have wood working tools you could make something I guess too.
Sorry, no great revelations, I know.
