So I got some nice Pelican cases from work and I want to make them into gun / ammo cases. The problem is that I need to replace the foam in them. I found the pick n pluck replacements but they are really expensive and I don't want to spend several hundred doing this. So I need suggestions on this. Most are about 18in x18in x 8in and I got 10 of them. I thought about expanding foam and trim it out but I want something I can change , reconfigure without a lot of work. So through out some thought. Thanks
