New StaBALL 6.5 Powder from Winchester — Temp Stable
Winchester has just introduced a new ball propellant, StaBALL 6.5, which it claims is very temp-stable. This means velocities and pressures should not vary greatly across a wide range of ambient temperatures. Winchester states: “StaBALL 6.5 is the world’s first temperature-insensitive Ball Powder, stable in extreme-hot or extreme-cold temperatures.” Winchester also claims StaBALL 6.5 can offer 30-200 fps greater velocities than other powders with similar burn rates. This new powder also has additives to reduce copper fouling. StaBALL 6.5’s burn rate and load density is good for popular cartridges such as .223 Rem, 6mm Creedmoor, 6.5×47 Lapua, 6.5 Creedmoor, and .270 Win. If StaBALL 6.5 can really deliver excellent metering, temp stability, more speed, AND less fouling — Winchester could really have a winner.
Metering Advantages of Ball Propellants
As there are existing very temp-stable extruded powders, such as Reloder 16 and H4350, what’s the big deal here? Well ball powders, with their small spherical granules, flow easily and meter well. This means ball powders can be thrown in manual powder measures with great precision. So StaBALL 6.5 could have advantages for hand-loaders using manual powder measures or progressive presses with mechanically-operated charge dispensers.

Winchester’s StaBALL 6.5 Product Description States:
StaBALL 6.5 is the world’s first temperature-insensitive BALL® Powder, stable in extreme-hot or -cold conditions. It provides optimal loading density in cartridges appropriate for the burn speed, which is ideal for 6mm Creedmoor, 6GT, 6.5 Creedmoor, 7MM-08, .270 Winchester, and many more.
Typical of a ball powder, precise metering contributes to improved velocity and pressure standard deviations, ingredients that are paramount to match grade accuracy!
This “environmentally green” propellant has copper fouling reducer additives, meaning longer durations of competition and field shooting without having to clean the bore. Precision accuracy throughout the match!
Velocity levels obtainable, depending on the cartridge, are 30-200 fps greater than other propellants in its class.
StaBALL 6.5 powder is available in 1 lb. and 8 lb. containers.
