Great suppressed SBR round
Shot extremely well out of all four of my 300BOs: three SBRs and one 16". I have tried quite a few different subsonic rounds with mixed results. These have never keyholed at any range unlike some more expensive rounds.

Cycles 9" SBR
Cycles flawlessly in my 9" sbr. Hand loads with lil gun powder don't, I have to use the slower burning CFEBLK. Whatever these are made with works well.

Great ammo
Shot this ammo suppressed in an SBR. The grouping was very good and was definitely acceptable for the expected range of an sbr. Frankly the groupings were as good as some ammo costing twice as much.

Works great
Shot these out of a stock Daniel Defense AR with a 16in barrel and a silencerco suppressor. The bolt cycling and the round hitting the target at 100yds was louder then the actual shot. Gun cycled perfectly and I had zeros issues. Can't wait to go to the range again. Great round for the money.
