Spare shells end up in the recycler more often than in the sky, and that is the costly way to clear a box. The ordinary recycler returns 15 of the 30 gun powder in a red boomer, and roughly half the low grade fuel and metal fragments too. A replacement later costs the whole bill again.
So craft for the night you have planned rather than a stack for some day. A few spares wait in a box without harm, and when red means something to your clan, like the defence on the item page, it pays to have one ready.
Only players who own the item can craft it, so a teammate without it cannot rebuild what you fed to the recycler.
