First off, if it was a TOUGH shot with her angling TOWARDS you, then you more than likely should have let her get, broadside, past you, turn or not have taken the shot at all. Thankfully you were able to recover her and at 12 yds, it should have blown through her. Fortunately, it was not a large buck for you more than likely would not recovered that animal.

Second, I have shot 100grn 1-3/8ths cut GrimReappers Razor Cuts since they have came out and have taken from elk to hogs with them. I shoot a Mathews Drenalin at 64lbs, 29-1/2" DL, GT Velocity XT's at 412grns out at 296fps.
Up till this past year I have not failed to recover an animal shot with these BH's and have pass throughs, with most as GrimReaper state, "Watch em drop". I lost a doe due to too high of entry and hit shoulder socket on far side, failing to exit.
I have taken literaly 100's of animals, hogs, bear and deer mainly, with them. I have tried the Razor Tips and agree with Big Eclipse, they do and will follow heavy bone or on a long angle, follow the bone and exit other than where they were intended. Main thing is to have enough kenetic energy as you are speaking of and I agree that you do. I have the 2" GR WT and they were only for turkeys. I feel that if l were shooting a heavier arrow, I would go to them for more kenetic energy.
