Does anyone have a good cast bullet load for a 280gr. Gas Check hard cast bullet. I am not looking for a cowboy load, I am looking for a hunting load for my new Winchester 1885 High wall Traditional Hunter, 28" barrel. Bore dia. is .377. Thanks for your time.

Here's some .375 Winchester load data.

This is NOT safe in older guns.

Should be OK with the upper Brinell hardness of lead alloy.
