    Chamber dimensions drawing of Browning 45 70 (Sporter Version)

    Does anyone know where I can find a drawing of the chamber dimensions of Browning 1885 Hi Wall in 45 70 Cal., 28 inch barrel sporter version? I believe the are different from the Black Powder version.

    If it is Browning it will have a standard SAAMI chamber.

    The rifling and twist is different for the BPCR. So far as I know the chambers are the same.

    But Wayne would be the final authority this side of Browning.
