We then have to reshoot them every 100,000 rounds to ensure they are still meeting this standard. Remington's Core-lokts have a required grouping of 1.5 inches at 100 yards if I remember correctly. So while shooting inside of 100 yds there isn't much difference, the longer range shots will start showing a noticeable difference in accuracy. As far as expansion, the SSTs are a little more consistent from bullet to bullet, but for the most part, bullet expansion is pretty similar between Remington, Hornady, and Winchester. If you really want a noticeable difference in performance across every metric, I would have to suggest looking into Hornady's ELD-X line. They're shot for match-grade accuracy, have a far more consistent expansion and penetration, and you will experience far less carbon fouling.
