Both cartidges are very common hunting cartridges in Norway. The practice of firing the shorter .308 cartridge means that the case will lack support against the chamber walls in the .30-06 chamber, which will deform the brass heavily during firing. This can be dangerous and cause a case head separation.
However, this big leap forward came at a price: it introduced an extra component into each round – the cartridge case – which had to be removed before the gun could be reloaded. While a flintlock, for example, is immediately ready to reload once it has been fired, adopting brass cartridge cases brought in the problems of extraction and ...
Components of a modern bottleneck rifle cartridge. Top-to-bottom: Copper-jacketed bullet, smokeless powder granules, rimless brass case, Boxer primer.. Handloading, or reloading, is the practice of making firearm cartridges by manually assembling the individual components (metallic/polymer case, primer, propellant and projectile), rather than purchasing mass-assembled, factory-loaded ...
When the firearm is out-of-battery, the round is not fully chambered, or the bolt face is not against the rear of the cartridge, and if the round is fired in this situation, the case will fail, causing high-pressure hot gases, bits of burning propellant, and fragments of the casing itself to be thrown at high speed from the firearm.
The brass does not provide a significant amount of strength, but the difference in appearance gives shooters a way to quickly differentiate between high and low powered ammunition. A 1908 depiction of a shotgun cartridge, showing a simple felt wad used to separate the powder (left) and shot (right)

To examine these weapons, investigators must fire them at a target at a controlled range with enough backing to stop the bullet and collect the spent round after it has been fired. [39] Once a known exemplar is produced, the evidence sample can be compared to the known by examining both at the same time with a comparison microscope.
[a] Gunshot residue can also be removed from surfaces by washing, wiping, or brushing it off, so a negative result cannot fully rule out a gun was not fired by the tested object or area. [6] Expelled gunshot residue does not travel very far from the muzzle because the particles lack momentum.
