Bear Guns: Some Facts and Musings
I just saw THE ultimate practical bear defense gun:
It's a new model Marlin in 45/70. It's stainless, has a straight stock in grey laminate, and I think the barrel is shorter than the previous "guide gun".
Shooters,
I am thinking about getting a larger capable rifle for elk and my dream of an Alaska hunt. This thread caught my eye. My cousin was treed by a grizzly and he now carries bear spray and a 44 Rem Mag pistol when he fly fishes in NW Montana. So we have talked about bear guns. The last thing one wants is to end up as dinner for a hungry grizzly!
I did a little analysis using Federals excellent free ballistic calculator (See:
http://www.federalpremium.com/default.asp?br=1.
I looked at the ammunition that generated the highest energy at muzzle and 50 meters. I assume that most man-bear life and death shootouts are in pretty close range. I looked at Popular Pistol, 12 Ga Shotgun, a few rifles that you would find hunters carrying. I included the 45-70 because I own one and it is a nostalgia weapon coming back into favor.
I am attaching the chart that shows the results. The 45-70 generates more twice the energy of the 44 Rem Mag (both with a 300 gr round). So if you are going to carry one weapon for bear defense the 45-70 rifle makes sense if you want a rifle instead of a pistol. But if you are hunting and want to be able to take down a bear, my Browning 30-06 generates 41% more enegy than the 45-70. I will not be carrying a shotgun if I am hunting in Montana or Alaska. But it is interesting to see that the best shotgun ammo only generates 12% more energy than the old 45-70.
In my case I think the 338 Win Mag makes a lot of sense as the main purpose is to be able to generate knock down energy on a flat trajectory out to 300 yards. It does that and still offers 61% more energy at the muzzle than the 45-70.
There one other factor that comes to mind. As a kid growing up in Montana, I read with great interest a number of books about bear attacks. One of the things that sticks in my mind is that in a number of cases, hunters who were attacked shot and then got a jam or failure to feed a round in a bolt action rifle. Clearly a result of panic and not taking a full return on the bolt. With lever actions, the more excited you get does not interfere with the loading of the round. What ever you are carrying it would be a good idea to try a few rapid fire practices at short range to make sure you can make the bolt, pump, or lever work and hit the target.
Fnally, when if the bear makes it through three rounds of 338 Win Mag and six round from my 44 Mag, as he opens his jaws to bite off my head, I will spit in his mouth. Supposedly, human spittle is to bears as quiche is to men. So if all else fails, and you can muster some spit in this situation, spit in his mouth and then play dead. Cause chances are you will be!
