300 whisper/300 aac blackout

[crracer_712]

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?

The subsonic rounds are really quiet, without a suppressor. My plan is to use my 9mm suppressor....

I have the horandy dies and they say 300 Black out/Whisper so I assume they will work fine. I was wanting Lee but they only made one run and dont plan on making more.
