Alliant Power Pro 4000MR

By S Peter P. on Dec 21, 2020
Works well in .243W with 87-105 bullets & .300 Win with 178-180 bullets. Meters well. Looks like some kind of extruded ball powder. No info on temperature sensitivity - I use something else when it gets over 90*. Data in Hornady manual & Alliant on-line.
