I haven't, and won't take the shot that we're discussing, I like to keep the odds in my favor as much as possible, BUT I have two friends that have tried it and both failed to recover the deer. Both got complete pass throughs, one used mechanical, the other fixed. Both had great blood trails to start with, but both blood trails faded to nothing, or so little that they could follow. They both tracked nearly 1/2 mile, and then did grid search from there. Neither recoveredan animal.
Both were relatively new at bow hunting, and they learned the hard way, that from now on, keep the odds in your favor, or pass on the shot! Why chance it?
Congrats to those of you who the shot worked for, BUT odds are that it will fail you eventually!
