Norma Ammo 308win Diamond Line 168gn

The barrel retains its accuracy more than twice as long when Norma Diamond Line is used from the outset. This is because Norma Diamond Line is coated with molybdenum disulphide and a protective layer of wax. Friction is reduced which means that the bullet travels further along the barrel before peak pressure is reached. The result is lower wear and improved accuracy. POA
