most target ammo is less expensive than defense ammo, but that lower price tag also means the ammunition is manufactured differently. Target ammo is primarily FMJ, or full metal jacket. This type of construction means that the bullet is likely to penetrate much further than defense ammo, and most target shooting ranges are designed for that result.
