I am interested to find out how many powders reloaders most commonly use to dial in their larger calibers/heavier bullets (6.5-284 to 338 RUM). I bring this up based on an earlier post under an 285 ELD-M heading. I have so many powders on my shelf I can't count them anymore but am able to dial in almost everything from 6.5-06 to 338 Edge with H-4831, H-1000 or Retumbo. Even found great load for 243 heavy bullets with Retumbo. I am just comfortable with the capability and limitations of these powders and don't spend the time/money necessary to experiment extensively with others. Wondering what powders others have as main players in their supply; may need to spend more time with those.
