This 163-entry comparison table provides vital information for hand-loaders. Note — this invaluable chart is not limited to Hodgdon and IMR propellants. This burn rate chart ranks powders from eight major powder-makers: Accurate, Alliant, Hodgdon, IMR, Norma, Ramshot (Western), Vihtavuori, and Winchester.
This chart provides useful information for all hand-loaders. When doing load development, and testing one powder versus another, it’s generally wise to choose propellants that share the same relative burn rate, as least for starters.
