Tough luck man, I dont care who you are if you hunt long enough it happens. Ive seen deer go forever on a one lung hit. It usualy does kill them but they can make it for a long time. I shot a small doe last year and hit her a tad high just clipping both lungs, and cut a major artery along the bottom of the spine. From my angle it looked good.There was blood spraying out as she ran off, but I had to sit in my stand and watch her flop around for close to 30 minutes before she fell into a creek and drowned. As for your choice in broadheads, rages are fine. Some people like bigcountry seem to be discusted with mechanicals which is fine but they do work. You just have to take into consideration the limitations of your equiptment. A mechanical isnt going to bust through a shoulder as relaibly as a fixed blade head but they still kill deer. I shot a big bodies 12 pointer with a G5 tekan last year and smoked both of his shoulders. He didnt go 40 yards.
