17pdr Brass Case specifications & 77mm HV

[TankGunner13]

I am doing some CAD drawings and was hoping you guyscould help me.
Does anyone know or have reference for the fine details of the dimensions of the brass shell cases of both the 17pdr and 77mm HV?Hopefully in the same manner that rifle reloading data is done.



I know the 17pdr is 76.2mmx583R and the 77mm HV is 76.2x420R just the other specific details

Thanks in advance
