Nice job on the deer Bill308
I personally don't feel that if a cup/core bullet happens to separate on occasion that it means it failed. More often than not, the core passed through and if/when you find the jacket its usually on the off side under the skin. I've shot at least 100 deer with cup / core style bullets with no issues. Sure, we'd love to have them stay together every time...but since they aren't bonded, that doesn't always happen. I've never killed any using XTP's, but they have proven to be a very reliable bullet. Deep Curls are better, but if you don't have any on hand you are out of luck right now.
