No, but I can point you to a study done at the request of The State of Alaska, which shows OC being more effective on bears - even grizzly bears than firearms. Even experienced hunters when faced with a charging bear often miss... I'm not sure how to post links from here at DSG, (have tried before unsuccessfully), but will certainly point you to plenty of research on the subject when I'm at my own computer. You never asked for specific research regarding black bear attacks in New England, (which is a rather silly point - black bears do not possess magic OC immunity powers), but will do some research on that bit of insignificant data for you if you need to... In the meantime, I'd love for you to do a test that I set up for a friend of mine who insisted he was better off with his .357 Magnum in the woods instead of OC. If you don't have access to a range with automatic target retrieval, I'd be happy to run this test for you if you ever come out this way. Set one upper half of a full sized silhouette at 25-yards. If safe, have this silhouette, so the head is about at your waist level, (I used a thin slat). Next, with a backpack on and your weapon holstered as if you were hiking, have a friend 'pluck' the overhead cable with some force to get the target swinging and hopping about and simultaneously hit the retrieve switch, (if safe). Unholster your weapon and unload it on the target before it gets to you. If you can, try to roleplay being completely surprised and having the shit scared out of you at the same time, (a little tough unless you're a method actor). Get back to us on how well you do, but remember - even a fast target retriever is not nearly as fast as a bear closing on you....Try this test and then tell me how safe you are with your 9mm....
I can't speak to your personal history, but can to my own. I have had many encounters with black bears in the woods and in my yard...many. I even had a few 'mock charges', with only one across the road from the Becket Transfer Station make a serious run at me...That bear closed a 75-yard gap in a few seconds. I barely had time to get my spray out and I'll be damned - it worked like a charm...I'm 99% sure had I gone for my Colt Defender, I would have missed...Many do....YMMV
