1873 Springfield
I have found an 1873 Springfield in my grandpas basement when I was doing some cleaning. The gun looks to be in excellent shape. My grandpa said he hasn't shot it in over 50 years. I did a very thorough cleaning and its load development time. I'm not familiar with this action or a 45-70 either which is what this is chambered in. I am debating on using some Trail Boss. Any load suggestions appreciated. CJ
