Winchester StaBALL HD
The slow-burning magnum member of the StaBALL family, matched to large-capacity magnum cases where loading density and metering consistency drive uniformity.
The slow member of the StaBALL family, for large magnum cases such as 6.5 PRC, .300 PRC and 7mm Remington Magnum, where a very slow powder plus high loading density is what buys uniformity. Same package as the rest of the line: temperature insensitivity, copper fouling reducer, and metering no extruded magnum powder can match. It is newer than its Retumbo-class competition and has far less accumulated user data behind it, so plan on developing it yourself rather than trusting a general reputation.

Grain shape
Spherical ball with a heavy deterrent treatment to get it this slow. The round grain is what lets you throw a large magnum charge repeatably and pack a big case densely, and those two things drive most of the consistency in this class.
Why geometry decides burn rate more than chemistry does: Shape Is the Product.
Part of the StaBALL family, marketed as temperature-insensitive double-base BALL POWDER that stays stable in extreme heat and cold. All StaBALL powders are REACH-compliant and carry copper fouling reducer additives that Winchester says extend the interval between bore cleanings. Made in the USA. Hodgdon flags it as both temperature stable and extra clean burning.
Burn rate
Very slow magnum rifle speed, slower than Hodgdon Retumbo and just faster than IMR Enduron 8133.
Chart agreement: consistent, but single-publisher - ranked only by Hodgdon (and echoed by the Wolfe/LoadData compilation). No second manufacturer's chart carries it, so the position is uncorroborated. Ranked by: Hodgdon, Wolfe/LoadData.
Powders charted near it — neighbours on the chart are not substitutes, and adjacency tells you nothing about what charge either one takes:
- Ramshot Magnum (position 184)
- Norma 217 (position 185)
- Hodgdon Retumbo (position 186)
- IMR Enduron 8133 (position 188)
- Vihtavuori N568 (position 189)
- Ramshot LRT (position 190)
