Limited to non-expanding bullets, I would opt for your model 638 and 158 gr semiwadcutters (SWC). Here in the USA there is a designation for higher-pressure loadings called +P (my apologies if you already know this), and I would use this. I am sure Fiocchi makes ammunition of this type, along with several US companies such as Speer.
