RE: 1 powder for muti-cals
Not me. I do not care how many different powders are on my reloading bench.
I mainly reload for fun, and to try and get the most accurate load I can.
I am by nature a cheap person, and like to save money like the next guy. However I do not scrimp on powder. After all I will eventually burn it all up. So why try to force yourself into one or two when there are so many available. However I will admit that there are probably more available than needed.
IMO there is more money wasted on different bullets, and expensive bullets, than powder. Tom.
