SilencerCo Omega .30 on a Rem 700 SPS Tactical AAC-SD in .308. Video was trimmed so you can hear noise differences. I think my audio cut out on the initial shot, as there's a large difference in person.
First two shots were supersonic - 150gr FMJ on top of 48gr RL15.
Final two shots were subsonics -220gr Nosler partition on 12gr Trailboss
