Interesting name, sonic booms. ?
Seismic ammo is taking conventional ammunition in a different direction. We believe a projectile with more mass traveling at subsonic velocities (900-1,000 fps depending on barrel length) is more effective than a lighter weight projectile traveling at a higher speed.
-is a little troubling to hear; makes me wonder why there is an exclusion for the H&Ks.Will your 9mm 185gr work in my gun?
We have tested our 9mm in multiple platforms and have yet to find anything that will not fire the round and cycle the firearm. However, we do recommend that you use a full-size pistol or carbine for optimum performance and velocity. Also we do not recommend our 9mm 185gr ammo for H&K™ USP, P2000, P30, or VP9 platforms. The MP5 performs well using the ammo.

Boutique ammunition not used by any law enforcement agency and will go the way of EXTREME SHOCK!!!! Fang Face Nytrillium ammunition.

I'm guessing because they have a polygonal bore? If that is the case, don't previous generations of Glock also have a polygonal bore, and should they be excluded?
They exclude the HKs and others because the velocity is a little low in these guns which results in sub-optimal expansion. They are working to correct that.
I tried some.
The bullet is seated long (because the bullet itself is long) and they failed the plunk test in some of my S&W M&Ps which have very short throats.
I experienced some high pressure signs. Primer flow, pierced primers, etc.
No explanation of what material they're using for the bullet itself. Wonder if it is still lead or something else?
They also say stainless steel cases, would they still have the small affect of increased wear people mention when they talk of Russian steel ammo?

No idea what kind of gun is a Kart. Or is that a typo?
