I have the Lee 300 aac blackout dies, will be reloading for my M&P 300 whisper. I have the complete camo rifle as well as the quad rail upper.
Just learning a little about this cartridge, but I've got 400 rounds of the Hornady 300 whisper ammo and assume it will be fine to use the spent brass with this die set for reloading, yes?
