The following information is just given here for anyone interested in it.
I used a micrometer on a loaded cartridge of each of the above noted calibres. I had old loaded cartridges, even the 30-30 was an old U M C (Union Metalic Cartridge Co.) The first list of figures will be for the 303 Savage, the next for the 30-30 and the last for the 30 Remington.

in the rest of the measurements.
Shoulder - .413 .401
Neck - .328 .328
Bullet that protruded from
the case .308 .308
