Sarg is right, this is my W.Richards .577 Snider.
This year I will shot it at last. Every time I beggan working on it something get in the way.
I have found a good load for my Kodiak .58" and, as soon as I can get a .600" mould, I will try to find its regulating load.
Next proyect will be my beloved 16Ga Ideal shotgun.
Sorry for been late but Im on vacation at the beach, far from my computer.

Thanks
Martin
