i can vouch for rage 2 blades. When i was young and dumb i didn't know much about KE, broadhead selection etc. Shooting a 45lb bow with normal rage 2 blades i took a quartering to me shot. Absolutely destroyed one of its lungs. Ran 20 yards up and piled up in front of my eyes. I got lucky with placement but i think the broadhead did its job.
I have buddies who say "i swear i saw the arrow go in right behind its shoulder". most of the time i dont even believe them. When we found his 2, they were both gut shot so its hard to believe someone over the internet saying they made a good shot.
I'm not saying your lying, but im not saying i believe you. It definitely could have been s deflection, bad shot placement, hitting a twig in flight, etc. I hope you can eventually recover your deer.
