My parents' house had a long, unobstructed stretch in the basement, and I set up a bullet trap at one end. I used to make gallery loads for my No. 1 .375 H&H to practice offhand shooting down there. WLR primer and 6 gr. of Red Dot, then I thumb seated a .375 round ball. I didn't need any neck tension, so I had a tool made to hand decap the brass without using the press.
