Buy Federal American Eagle Suppressor Ammunition 300 AAC Blackout Subsonic 220 Grain Open Tip Match. Federal American Eagle Suppressor Ammunition was designed from the ground up to provide the ultimate in reliability and cleanliness in suppressed firearms. The ballisticians at Federal Premium tailored each load for suppressor usage; each load has the cleanest, fastest burning powder for that caliber to help keep suppressed firearms as clean as possible while maintaining subsonic velocities. The bullet weights and profiles selected for each round were chosen to give each load the most consistent, accurate performance of any suppressor specific ammunition on the market. Subsonic loads are ideal for shooting through suppressors because they help reduce the sound signature even more. Subsonic rounds do not exhibit a supersonic crack making them quieter when shot through your favorite can. This ammunition does not have to be fired through a suppressed firearm and will function in non-suppressed firearms. This ammunition is new production, non-corrosive, in boxer primed reloadable brass cases. Buy Federal American Eagle Suppressor Ammunition 300 AAC Blackout Subsonic 220 Grain Open Tip Match
