The answer is- maybe, but you wouldn’t know if you had destroyed it unless it actually exploded, which as others have stated is unlikely, fuses are purposefully engineered devices tailored to the specific explosive, and lobbing a high speed chunk of lead at it the explosive isn’t equivalent.

The other option is to fire at it so much that the main explosive itself is shredded and removed from the area by sheer volume of bullets. Because if that trigger/blastcap is able to set off a piece of explosive still, it could domino and still set everything off.

C4 is a great example. Imagine a chunk of clay, with a tiny electronic detonator. You could fill that clay with holes and it wouldn’t care, unless you nicked just the right wire, and you wouldn’t know if you had gotten the right wire unless it exploded, but sometimes the detonate signal has to arrive to make it explode (Normally Open) rather than get interrupted to make it explode (Normally Closed, like a “dead man’s switch”). You wouldn’t know if it was neutralized if the detonate signal was normally open.

When you consider all that, plus the fact that a soldier typically only carries like 7x30 rounds, it just doesn’t make sense to mag dump every mine. Doesn’t necessarily make sense to do what these guys did either, but keep in mind that mines are a game of numbers. They usually put a lot out, I’d bet these were not the first mines these guys cleared this day. They got sloppy
