SUBSONIC 300BLK - Lapua 200gr FMJ - Standard Load

Subsonic 300 Blackout - Lapua 200gr FMJ round using new Jagemann brass with the Ammo Inc stamp. This load is optimized for 16" rifles but achieves decent velocities from SBRs.

MOQ 200rds.

We've tested this ammunition to validate the factory claims (which is 1,090fps from a 16" bbl).  They're right on.  Long-barrel shooters will find this to be very consistent ammunition.

Average velocity for our 20-round string is 1,088 FPS.  Standard deviation is 11 fps with an extreme spread of 50 fps (1,068 fps - 1,118 fps).  We didn't shoot paper for groups but we effortlessly hit a 6" hanging steel target over and over again at 200yds.  We used a Magnetospeed chrono for all measurements.

We shot for chrono numbers from an unsuppressed 8" upper.  Our chrono gave us an average a little north of 1,000 fps with a standard deviation of 75 fps.  Cycling was not a problem.  This makes for a very good subsonic plinking round from an SBR.  The SBR loading delivers better performance for SBR shooters looking for a precision round.

The brass is top tier and reloaders will get long life from it.
