Work much better than the “name brand” subs that I have used. These actually cycle and don’t fall apart like the other ones.Jason H.19 Aug 2024
Some of these were subsonic out of 10” cmmg ps90 barrel. Some just over subsonic. Which defeats the purpose for meBen C.13 Aug 2024
My favorite 5.7 subsonic load for the Mk57 Banshee. Wish SB193 was more available. If you are zeroed for supers make sure you know your holds with these subs.

I found Detroit Ammo's Subsonic 5.7x28mm 55gr FMJ rounds to be decent overall, but I encountered some issues with cycling in my pistol. While the accuracy was acceptable, the rounds occasionally failed to cycle properly, leading to occasional jams. While they performed adequately in other firearms, this issue was disappointing and affected my overall experience.Precision S.20 Sep 2023
