I was hoping to get some help. I am building a 9 mm open gun. This will be my first open gun. Mainly STI parts with a Brazzo slide.
I am looking for some help with the load I don't really want to shoot major but for the moment for the gun to work during testing.
I will be using a 125 g moly coated bullet. With auto comp powder.
Any suggestions would be great. Thank you for your help
