Got another packaged in the mail. This one contained the bullets and sabots I ordered:

500 Berry's Plated 200 grain .452" HP
40 Barnes 200 grain .451" XPB
150 Harvester Crushed Rib 50-45 cal sabots

Check out the size of the hollow point cavity in the Barnes bullets:

I expect full expansion even on a longer range hit with these things.
