Will be interesting to see these tested down the road. Depending on the bullet design, they might have something....or not 😂

None of their data states what velocity they are making.  Heavier than normal means less case capacity and possibly higher pressures.
It would be interesting to see the actual velocities with various barrel lengths...    

PRODUCT INFO
Seismic's QuakeMakerTM +M 9mm NATO bullets are heavier and deliver
far greater momentum than any other 9mm, and at subsonic velocities, they're ideal for suppressors.

Thanks, I did email them regarding the bullet manufacture, but nothing back yet. Not going to hold my breath on this one.
Thanks
