Hello. I shot some a while back from a Hi Power and the average velocity was 1134 ft/sec. It expanded fine in water and wetpack, but is the "old technology" jacketed hollow point. In more recent times the only Remington "Express" load I've tried has been their 115-gr. JHP +P. I would suspect that the standard pressure JHP in the slightly heavier weight would perform in similar fashion to the Federal 115-gr. JHP in standard pressure. Remington has altered their line of 9mm JHP ammo in recent years.
Best.
