I just built a shed and dedicated an 8' shelf unit to storing target backers, range stuff, milk jugs, etc., for my little home range. I have several different types of paper targets and was wondering if anyone had any decent ideas on how to storage or organize them? I've got them in an old brine tank from my old softener, but they have to be rolled up. Plus, the lid is a pain in the ass to get off, but does keep the spiders out. Was thinking about making another shelf unit about 4' wide with several shelves to organize them flat, but that's going to take up a lot of space.
