I load for .41 Mag with 210 grain bullets. I like AA#9. I use it in my .30 carbine loads as well. It is cleaner than Alliant 2400 especialy with the midrange loads. If you want to go hot with it you can do that as well. It is great for mid range to full magnum loads. 2400 works though it is very sooty in the midrange loads, and kind of sooty on the upper end.
If you are looking for a good powder for low end loads that burns clean, and gives great casse fill Trail Boss is a great one.
No matter how many times you do it and nothing happens it only takes something going wrong one time to kill you.
