190gr sub x
Great price and worked great. Ordered more and I plan on trying other 300 from Phantom as I am now a happy customer.

Great ammo! Whisper Quiet!
Works flawlessly in my 7.5" 1:8 twist PDW. I generally don't go over 190gr because of the twist in this upper. This stuff performs flawlessly. Will, and have, order more.

300 blk 190gr sub x
Could not ask for better. My Daniel Defense pdw loved them. Super accurate and quiet. I used a yhm 30cal resonator k suppressor with Qd break

190 gr sub x
Very happy with the value of this product... Good subsonic home defense round for barely over .63 cents a round? These are usually $30 for a box of 20 in the big box stores! Great value and Phantom Defense was great to work with

Great bang for the buck
The 300blk bolt action loves 'em and even better, the 5.5" Rattler eats them up! I'll be nabbing these every time they're in stock.

Amazing
Shot with a brn-180 gen 3, 9"barrel suppressed with an OCL Polonium 30. Cycled great, consistent subsonic velocity, great expansion. Best part, they're cheaper than subsonic plinking ammo from other manufacturers. I'm buying a whole lot more.
