S&W M&P .300 Whisper/AAC BLK

[redneck419]

Does anyone have any experience with one of these? Will it handle both equally? I'm looking to go subsonic with a suppressor. I know it's almost the same round but it's the 'almost' part I'm concerned about. The Blackout is the preference due to commercially available brass.

I'm a S&W guy owning a couple of M&P pistols and and revolvers.

Any response will be appreciated.

i built a bolt action blackout.
i can and have shot whisper ammo in mine.
i have been told whisper will work in a blackout
blackout will not work in a whisper
you might talk with S&W first.
but i have done it in my bolt gun

And here I thought they were the same thing.

whisper will work in blackout just fine... blackout is a tad longer

I see no need to run the whisper round when the blackout is so much more avalible . I can verify the smith and wesson will run sub sonic and supersonic with or with out a suppersor .
