I bought 6 different types of ammo to shoot through a suppressed Ruger American. This was the loudest out of the sub sonic rounds. The grouping was second best behind the 208 gr Hornady Black. The black was much quieter and held very tight groups.

Ammo is accurate but had multiple failure to feed issues with AR platform

Very quiet ammo. In stock at Buds. I buy ammo and my guns at Buds. Have a question on any item? Call or email answers back in short time.

These 190gr Sub-X rounds performed the best in accuracy out of the box compared with four other subsonic rounds I tested recently to see which I would purchase for tarining and HD use. That accuracy and the hollow point design make this round my preference.

Favorite bullets to shoot suppressed that still pack a punch

Hornady is top notch to begin with. Very accurate and works on hogs. As always, extremely fast shipping by Buds!

There’s nothing wrong with this ammo. I just prefer at least 208 gr.

first time trying out these rounds are great for my 300 blackout and I had no malfunction or problems shooting. Definitely will be getting more of these rounds again.

cycles well and accurate throughout the day. First time using subsonic ammunition and was surprised by it. Will be purchasing more soon.
