There are several reasons to reload ammunition.
Save Money
Typically, reloaded ammunition is significantly less expensive than factory ammunition; usually you can save between 25%-60%. This allows one to shoot more for the same amount of money.
Customize Your Load
Another reason to reload is for customization; for hunting and competitive shooting, one can assemble ammunition specific to a task, or for a specific firearm, that frequently cannot be bought. As an example, there are a variety of custom projectiles available for hunting big game that are simply unavailable in factory ammunition.
Quality Ammo
Most competitive handgun shooters need ammunition with softer, easier to ignite primers, as their firearms have been modified by a gunsmith to provide a lighter trigger pull. Some shooting sports require a power factor of competitors’ ammunition, power factor being the bullet weight times the velocity, with perhaps another factor introduced. Factory ammunition is often more powerful than needed in some calibers, in others it is not powerful enough.
Some consider reloading to be an enjoyable pastime by itself. They try different combinations of brass case, projectile, powder, primer, variations in projectile seating depth, etc., to get the best possible group.
