That is a great post/example. There is always a lot of emotion in these bullet performance threads. To the point that "haters" and "lovers" are often labeled. Derek M has it pegged - people struggle to understand when others have different experiences with the same brand/type of bullet. But as someone posted earlier, edited word here happens.
Pick your favorite flavor of bullet and someone has had a bad experience. It doesn't mean it is automatically their fault. It also doesn't automatically mean a company is duping or tricking you. While I am NOT a big fan of revising threads for content (language is one thing), sharing your experience in a less emotional way (good or bad) tends to lend credibility to your point of view.
FWIW, I put a chest shot on a doe with a 168 classic hunter last weekend. I definitely had expansion, and massive trauma, and a large exit - and I still found her 110 yards away. Crazy EWH.
Hope your experience doesn't completely jade you to these bullets. IMHO they have their place and based on most of the feedback I read your experience was the exception, not the norm. Still sucks, but glad you harvested the animal.
