When changing a rivet dies on a rivet gun, you should make sure

Installing solid rivets in an aircraft structure requires considerably more know-how and skill than does working with pop rivets. For one thing, you can install those hollow-core pop rivets working alone with only a simple hand operated pop riveter . . . even if you don't have access to the back side of the parts being riveted together. It is sometimes called "blind riveting".

Unfortunately, it's quite different with solid rivets. You do not enjoy the luxury of that pop rivet "blind" feature because you absolutely must have access to both sides of the parts being riveted. Sometimes it even takes two people. Furthermore, you will have to become proficient in the use of a few special tools.
