Winchester canister propellants are spherical BALL POWDER products made in the USA; the round kernels meter precisely through volumetric powder measures. Winchester credits its flow characteristics as an advantage over other powders of similar burn rate. It is generally understood to be the same propellant as Hodgdon H414. Not listed as temperature stable.
Burn rate
Medium-slow rifle speed, slower than Hodgdon H380 and faster than IMR 4350.
Chart agreement: consistent on position; note that Vihtavuori, Shooters World and Wolfe/LoadData all pair Winchester 760 with Hodgdon H414 at the same burn rate step, while Hodgdon's own chart lists 760 but omits H414. Ranked by: Hodgdon, Vihtavuori, Shooters World, Wolfe/LoadData.
