Here is an idea for people who use the quick fire breach so you can use high explosive or other fused shells.

You could make it so the shell could be pre fused in a crafting table or by shift right clicking with the fuse in the off hand slot and shell in the main hand slot.

Maybe for balancing you can only have one per slot as default or in config you can change it to a stack if you want to.

This is just a suggestion so don't feel pressured to implement it.

Shells can already be pre-fused, broken and picked back up for later use. It would be opportune to state this both in the summary of the fuses, and in the ponder animation about fuzing munitions (probably with a mechanical drill to show the most likely automation use case).
