I've seen them do that with other calibers as well, no problem...I've killed about 85-90 with the .243 and CoreLokts out to 300 yards...If your shots do run on the longer side, you might want to try the Federal Premium loading in the 85gr HPBT Sierra GameKing...It starts out at 3300 fps, which helps it mushroom further out...
I killed a decent buck this year at 277 yards with a CoreLokt, deer dropped on the spot...
At what point in killing the deer within 50-60 yards did the bullet or caliber let you down???
