[hermosabeach]

I know nothing about this round other than it was launched at SHOT a while back

has anyone gotten hands on with a round that probably is more obscure that 5.7 and .460 Rowland?

What the 9mm -357 sig weak as it’s based on the .40

Is this a 10mm necked down to 7.5?

There's a plastic one now:



Cool, but I could never afford to feed it.

American Rifleman says that cartridge case is a stand-alone design not derived from any other caliber:

An Official Journal Of The NRA | Tested: The FK BRNO Field Pistol

A 95-gr. bullet moving at more than 2000 f.p.s., isn’t news—unless it’s fired from a handgun. The new, beautifully machined FK Brno Field Pistol and its 7.5x27 mm cartridge push the design and performance envelope. We’ll warn you, though, it’s spendy.

The 7.5 FK is a bottleneck design, 35 mm in overall length according to CIP (Europe’s version of SAAMI) specifications. The cartridge could be aptly described as the 7.5x27 mm, as that’s the case length. It is important to note that there is no parent cartridge to the 7.5; it is a case design all of its own. The 95-gr. solid-copper hollow-point bullets clear the muzzle at an advertised 2000 f.p.s., resulting in 844 ft.-lbs. of energy. At 100 meters, the bullet is still traveling at 1525 f.p.s. and producing 491 ft.-lbs. To accomplish this, the 7.5 FK operates at 50,570 p.s.i., which is higher than nearly any handgun cartridge on the market today with the exception of the .454 Casull. This thing is hot.
