NORMA CASES 7MM-08 (100)
7 mm – 08 Rem.
The 7mm-08 is nothing but the .308 Winchester necked down to 7 mm or .284”. This wildcat was adopted by Remington in 1980.
The 7mm-08 is closely connected with metallic silhouette shooting. This sport has a Mexican origin and the trick is to knock down animal-shaped targets made of iron plate. The targets are placed from standing between 100 and up to 500 meters from the riflemen. The shooting is done off-hand. Accordingly the demands for a metallic silhouette cartridge were all met by developing the 7mm-08. It has a high precision potential, a flat trajectory, a light recoil and sufficient power to knock over the silhouette even when hit at the extreme range.
The case capacity of the 7mm-08 is slightly smaller than in the 7×57, and accordingly the muzzle velocity of the heavier bullets will be 100-150 fps. less than in the Mauser design.
For hunting purposes this cartridge is well-suited to medium game at long range and therefore also a popular choice for light-weight mountain rifles as it works well in short actions.
Norma products are known worldwide for high quality. Cartridge cases are an important factor in this reputation. Superior quality ensures a long life and many reloads. Norma cases are made of the best possible raw materials with the narrowest tolerances, and they deliver accuracy round after round.
The case neck is annealed to become softer. This prevents gas leaks and enables the case to hold the bullet firmly for at least 10 years without cracking as a result of aging material.
Further down on the case body, the hardness increases to avoid unnecessary stretching. If it is too hard, it would bring the risk of cracks.
Furthest down, around the primer pocket, the brass should be firm. Here, the hardness is nearly twice that of around the neck.
The structure of the material reveals the hardness. During processing the large, soft grains are broken down into smaller ones, which makes for a harder material. At the annealing, small grains become bigger and the hardness decreases.
