I just had some great results at the range with my 30-06 and uber slow powders (H-1000 and Retumbo) now the question is how low can you go on the powder charge and not have a dangerous situation? I was thinking to look at loads for magnum calibers and see the start charges there and figure up the case volume, but I dont think that would be an equal comparison.
I was shooting with 57 gr of each powder and that gave about .010 compression with a seated boolit, without filler how low can I take this charge?
