Got the crate from a guy at the range who was going to put it in the dumpster. The 1/8 board for the dividers and the 1/4 popular for the spacers was free, made out of scraps. Justa few 5/8 nails and done. It holds 10 mags loaded and 16 boxes of ammo. Total ammo count 620 rounds. Perfect for the range or a SHTF box. I love free!
