I have had the good fortune to hunt many places around the world and have taken hundreds of game animals of all shapes and sizes. Bullet failure is about as common as a free lunch. I have only seen a few and here again, the bullets did not fail as such but were of the wrong type for the job. Things like people using a 90 grain hollow point in their 270 for mule deer. With the proper choice of bullet and the proper shot placement, bullet failures in my opinion just don't happen. By far, choosing the wrong bullet is the cause of 99.9 percent of failures. Poor shot placement is usually the reason for animals that run away. The corlokt has been around way to long for it not to be a pretty good game taker. Either that or there are a lot of less than rocket science hunters because Remington has sold thousands of train loads of them.
