Hodgdon IMR Winchester Burn Rate Powder speed table relative table chart

Hey guys, you’ll probably want to download this Powder Burn Rate Chart issued by Hodgdon/IMR. This table includes the latest IMR powders including the Enduron series (IMR 4166, 4451, 4955, 7977), shown in green below. Please note, the chart is not limited to Hodgdon and IMR propellants. This table also includes popular powders from Accurate, Alliant, Norma, Ramshot (Western), Vihtavuori, and Winchester. There are a total of 163 powders listed in the chart.

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. While this chart contains “Nov. 2019″ in the title, this is the most recent chart available from Hodgdon/IMR. It is the chart currently linked on the Reference Data Center.

NOTE: Hodgdon powders are shown in blue, IMR standard powders are shown in yellow, IMR Enduron powders are shown in green, and Winchester powder are shown in red. DOWNLOAD Chart HERE.

Burn Rate Chart from with 197 Powders burn rate chart
The website has released its own burn rate chart, which is even more comprehensive than the official Hodgdon/IMR chart. We recommend starting with the Hodgdon/IMR listings, but if you can’t find a particular powder on the Hodgdon/IMR chart above, then consult the alternative from which lists 197 powders.

We also caution that, with any powder, start conservatively, at the low end of official load recommendations. Be aware that, even within the same burn range a ball powder can behave differently than an extruded powder. And some powders are much more temperature sensitive than others. Among the available powders on the market, some of best in terms of temp stability are the Alliant TS (temp stable) series, and the popular Hodgdon powders, such as H4350, made by ADI in Australia.
