[6x45]

Anyone messed with this type of case? I’m really curious if theses cases can be necked up or fire formed into 223ai?

WTF

The bullet will only require a light crimp (we’d recommend a slight crimp using a Lee Collet Factory Crimp Die) – the nickel alloy used in our case cylinder has a much higher tensile strength than brass and does not require the bullet be seated as deeply or crimped as hard as brass. If you find the bullet spins or appears lose after crimping it is a strong indication that the bullet is seated too deep in the case.
