Strike depth
The diagram below displays a cartridge case that has been shot. The indent, where the firing pin has hit the cartridge, is called a strike.
It is important to measure the strike depth on the cartridge because this is the point where the primer is activated.
A minimum strike depth is necessary to transmit sufficient energy to the primer to cause its ignition and ensure that the cartridge does not misfire.
The ideal strike depth for an ELEY cartridge is between 0.012–0.015 in. This depth can be measured using a strike depth gauge.
