I have to laugh, because you asking about carrying your shells , if you listen to most of the guys on this forum , they leave the truck with either 1 - 3 shells , they don't carry any extras shell. I learned years ago , that's why i buy shells is to carry few extra, never know , what you might run into in the woods , this day and time. I know this isn't the question you asked .. sorry, just giving you perspective from being on the forum.
