Wow, CG! I gotta admit, I haven't followed your postings enough to know if you're a straight-up fella or not, but this thread makes me wonder...
I know you'll take offense at some of the responses you're going to get on this one, and it's certainly not my intent to start a personal attack on you -- not in the least. As eightwgt said, it's not my style. And I know you said you had no perceived agenda or vendetta against mechanicals, but honestly, someone who did and was trying to cast doubt on that tool wouldn't admit it in the same breath as his "data" anyway...
Rather, I'd just like to compare your stories with the hundreds and hundreds of successful usages reported by literally scores of other hunters on this board and elsewhere. I have never had a mechanical fail on me since using them, and I have had shots blast through shoulder blades of some very, very tough Illinois whitetails. I have also watched as my mechanical nearly split a hen turkey's neck into. Hard or soft, it doesn't seem to matter.
As far as the "tip of the Snyper was bent fully 90 degrees," I gotta admit, that one just makes me wonder. I went to Rocky Mountain's website,
www.rockymtbroadheads.com, and clicked on Snyper. Rocky Mountain provides some good photo footage to explain how their head works. One of the things I noticed is that the end of the ferrule duplicates the shape of the tip, and comes right down to the end of the blade -- thereby reinforcing it, and, I would think, not really allowing the blade to bend at a 90-degree angle. There's just not enough of the blade exposed. Maybe your pictures you said you would post will clear this up, and I sincerely hope they do.
And to think that type of failure would happen as a result of a neck shot (I'll let eightwt's post speak for my thoughts on these shot placements)... I just don't think the neck of a dog is tough enough to bend metal. Sorry, just calling it like I see it here. Maybe I'm wrong, but a twenty-yard shot at a horse's neck shouldn't damage one of these heads, much less a small dog.
Again, not meaning to stir up a hornet's nest with this one, and for all I know, you may be an outstanding guy. And I hope you are. The stories just don't match up with anything else I've ever heard about mechanicals.
