Anyone shoot this round yet and if so must it be a suppressed rifle ?

BEST ANSWER: why buy this if you are not running a suppressor? anything subsonic is designed for cans. if you are running unsuppressed you should go with lighter grain supersonic rounds
What is the velocity? Subsonic covers a wide range!

BEST ANSWER: Magtech’s website says 1017 fps out of a 16” barrel for this product ID 300BLKSUBA.
I've heard these Magtech 300 sub rounds have a tendency to keyhole, has anyone shot them at distance to see if they start to wobble?
Jason R on Apr 11, 2019
BEST ANSWER: I haven’t seen any and I’ve been shooting paper at 100 yards.
In my experience, subsonic .223/5.56 is not po werful enough to cycle the action. Does any know if this will cycle? How’bout if suppressed?

BEST ANSWER: suppressors generally help to cycle actions better.
Does anyone have any accuracy experience with this ammo? How does it fair at 50 and 100? Thanks?

Great value!
These cycle fine in my unsuppressed 8.5” PSA Shockwave pistol. Buying another 10 boxes right now!
