I have always wanted to ask a bear spray expert, how does one deploy the spray when the bear is upwind?
The spray comes out at appx. 30 mph. So, the wind would, logically, have to be greater than 30 mph. Also, the spray is heavier than air, so it has more momentum/inertia.
Wind speeds like that, if coming from the side, could deflect a relatively slow moving, large caliber handgun bullet, and likely prevent accurate shot placement, especially when rushed and stressed. As I said, I have been charged and doubt if I could have accurately hit a running bear. Standard firearms training is to place a target inside a tire and roll it down hill. To pass, you must hit at least once with a 375 H & H Mag or 12 gauge with slugs and sights. Similarly, a target on a downhill pulley coming towards you at 35 mph with one hit in the kill zone in 5 seconds, with a 44 magnum. Our biologists at the Alaskan NWRs use 2 3/4 Brenneke slugs when they have to destroy a bear in "defense of life or property" (meaning after an attack), otherwise they carry spray.
Someone said:
"It has nothing to do with bravado, it all comes down to experience, and I have none with Bear Spray, ergo I prefer to stick to what I know, what I'm confident with, and what I'm proficient with. Besides, in a pinch, I would prefer a potentially lethal weapon to a strictly nonlethal weapon, because on the off chance that I encounter one of the 8% of bears that don't stop after receiving a spray to the face, I know that they won't respond quite as well to a free blast to the face with a powerful gun."
Answer: What if it is one of the 38% that a firearm doesn't stop? Even a "blast to the face" may not stop a bear Bear skulls are thick and slope so as to deflect a bullet if not straight into the nasal cavity and if deflected it may not kill instantly. Even if a "kill shot" the bear may still travel 50 yards at 35 mph. Want to get hit by a 800-1000 lb bear at that speed? How much experience do you have with hitting a CHARGING 800 lb bear?
With my Reeder Super Blackhawk in 454 Casull with 325gr hardcast, I can place two shots within a 2" group within 5 seconds-after that my group opens up! I still carry spray!
Again, do what you want! Just sharing my experience and knowledge! I would recommend hard cast bullets in the heaviest weight you can find: my woods guns are the aforementioned Reeder, an OM Blackhawk in 45 long colt and my Glock 20.
