With the advent of chemical primers, it was not long before several systems were invented with many different ways of combining bullet, powder, and primer into a single package which could be loaded quickly from the breech of the firearm.

Handloading ammunition avoids the labor costs of commercial production lines, reducing the expenditure to only the cost of purchasing components and equipment.Reloading may not be cost effective for occasional shooters, as it takes time to recoup the cost of needed equipment, but those who shoot more frequently will see cost-savings over time, as the brass cartridge cases and shotgun shell ...
It is easy to remove and replace Boxer primers using standard reloading tools, facilitating reuse. Some European- and Asian-manufactured military and sporting ammunition uses Berdan primers. Removing the spent primer from (decapping) these cases requires the use of a special tool because the primer anvil (on which the primer compound is crushed ...
Tests comparing lead-free primers to lead-based primers conducted by the US Department of Defense (approx 2006), exposed significant differences (at the time) in reliability between the two primer types, when used in 7.62×51mm ammunition. In these tests, lead-free primers were proven to be not as reliable as lead-based primers.
