The Wilson Combat 300 Blackout 220gr Sierra HPBT subsonic load is a box of 20 rounds loaded with a Sierra hollow point boat tail bullet for subsonic shooting (Wilson Combat part no. A300BLK220HPBT). Wilson Combat describes the load as match accuracy and reliability for subsonic use, using Sierra legendary MatchKing bullets for the ultimate in accuracy, and lists it for target and match shooting as well as subsonic use. The 220-grain hollow point boat tail leaves a 16-inch test barrel at 1025 fps, below the speed of sound, and the bullet carries a 0.608 ballistic coefficient. Wilson Combat loads these rounds with USA-made brass cases, clean burning low-flash powders and hand inspection at its facility in Berryville, Arkansas. Each box holds 20 rounds, enough for a zeroing session and some follow-up shooting.
