This is an online calculator to illustrate the actual cost of reloading.
The calculator was specifically for rifle reloading, but can also be used for pistol reloads.
It takes into account the cost of casting, and compares the reloaded round cost to the cost of factory ammo.
This can tell you how many reloads you can expect to produce before you recover the cost of the reloading equipment.
