Anecdotal regarding the SS90

The 23gr SS90 load was dropped a few years back due in part to concerns about locating the projectile's plastic core in x-rays. The replacement 31gr SS190 has a dual core of aluminum and steel, which runs afoul of laws regarding armor-percing projectiles in handgun cartridges. The SS190 runs about 2300fps from the P90 and around 10-15% less out of the Five-seveN pistol.Say, does anyone have data on the short-lived sabotted sub-caliber 'HV' round for the 5.7x28mm? This died even faster than the SS90.
