Truth is that if Blocks had "in spec" chambers, instead of being the size of a one-car garage, you wouldn't be hearing any more mis-information being spewed about the .40 than any other other cartridge.
Block's are known for unsupported chambers and bulged the brass "badly".. Had seen reports of some ruptured cases IIRC..

I shoot 10mm with a 1076 and an EAA Witness.. barrel chambers are fully supported and the brass has a reload life like 45ACP 20+ times each.
