I've killed them with a 270, 30-06, 30-30, shotgun, .50cal muzzleloader, 357 Max pistol and a bow. They all work when they hit the right place. Your deer only traveled 15 yards after being heart shot. Sounds like the gun and bullet worked flawlessly. Who cares about a blood trail when they only go 15 yards. That said, I have used Remington core-lokts in my 243 and they seem to work fine. I've also had good luck with Federal Fusion 100 grains.
Everything I've ever shot them with has at times left me with deer that left absolutely no blood trail. That's why it's so important to assume a hit on every deer shot at.
