10mm for Grizzly protection

[gandog56]

I mean I'm sorry. I love my 10mm pistols, but if mean Mr. Grizzly is around, I want my .454 Casull!

10mm would be viable defense for Black bears and maybe medium browns but this thing is a beast. I'd want a 12 gauge or Barret .50 for this beast.

That's a huge bear!  I've never seen tracks THAT big! 

If you're going to be in the deep back country, you're going to be carrying...

Bear Spray... if you're a backpacker/climber.

12ga with slugs if you're an outfitter. Or some big bore rifle with hard cast or high velocity, hard hitting ammo.

The 10mm... purely backup... totally last resort.

Seriously this is the gun I would pack with a light to attach and I would carry hardball in first barrel and a foster slug in barrel two.

Back up model 20 stoked with FMJ 165grain flat point loaded to their full potential. I choose the 10 over a 454 or larger because the 10 is far more controllable follow up shot capable.

Good quality tacticle sling will allow you to carry that shotgun easily and get it into action quickly.

I have one have literally put 500+ rounds of slugs and 00 buck through it no issues.

The other gun I would add to the mix us a SBR or carbine in 458 SOCOM

I guess it would be better than a .22.

I still prefer my .454 Casull, though.

Anymore questions why you need a BIGGER one and maybe the 10mm as a back-up? 

What caliber was used to shoot that bear?

A tranquilizer gun with a heavy dose! It was tagged...

 I have a lot of experience in densely populated brown bear country.  Quite remote.  . I've shot for my life with a 44 mag,  320gr Cast Performance WLN pushed by 20+ gr H110 from a 5 1/2" Redhawk.  Not a very big brown bear.  I didn't get bit ect.  But I was very underwhelmed with the handgun.  Finished that fight with my 458. I've also stopped charges with the 416s and 458 Win Mag.  Those are absolutely decisive  !
Not trying to start a rouw but the 12 ga. SUCKS at stopping/dumping brown bear.  Unless your using special slugs like the Heavy Brenneke high velocity slugs. Then its like a 45/70. With buckshot you will get very shallow penetration.  The typical deer slugs only penetrate 6-8" and won't smash a brown bears shoulder. 
A 375 works good but the 416s and 458 work spectacularly. 

I've been in far too many of these brown bear threads I usually avoid them anymore. 
I've had and packed revolvers up to the 480 Ruger Super Redhawk.  Which is one of my favorites as I can shoot it ok with a 400+ gr bullet at 1200 fps. 
The 500 Smith +Wesson with 400+ grain bullets at high velocity works very well.  Better than any shotgun I've ever seen.
  Tho I don't live and work.in dense brown bear country now. If I did I would pack my G20.  Loaded with the same 220 gr Hard cast Buffalo Bore TC bullet.  Just like I do here.  The reason is.  I get good hits with it.  Hits are what count.  But when Im in brown bear country I also pack a dead reliable crf bolt rifle in 338 Win Mag or larger

 Threoys abound with bear defense threads.  But flat charges are EXTREMELY RARE  !!!!!
Usually a bear that is a punk adolescent will root and beller around trying to work.up the courage to give u a go. Or a sow is protecting but mostly teaching her cubs how to deal with the 2 legged problem.  Over 90% of the time you have plenty of time to get your gun ready.  Just backing off teaches bears to push you.  Just like dealing with an aggressive dog.   
Thru my experience with brown bear,  I've learned that bolt rifles in 416 or 458 are the best tool to have.  For those new to dealing with bears,  if they are good buddies with their big bore rifle.  They will have the confidence torun the bear, bears off without a shot being fired. 
Ime the attitude and demeanor of a Marine Corps drill Sargent is the best to have to train brown bear to fear man. Which is the only correct response a bear should have with a human.  If all you have is a G20  then you just gotta have abit more intestinal fortitude.  I've done it several times with short barreled 357 mag revolver,  S+W Sigma in 40 S+W,  41 mag,  44 mag,  45 Colt and 480 Ruger handguns. 
Bumping into a bear the size of the one pictured is a very rare event. 
The most dangerous bears are the old ones that are starving.  They plan to eat you and only their death will stop them.  Those are the bears you really need to have your S#!+ together on.
Since a chambered,  safed  rifle in your hands is faster to get off an accurate shot than a handgun in a holster.  That is how I pack mine.  Also why I use the Ruger M77 Mk2 actioned rifles.  They are the safest rifles there are when on full safe and have the half safe feature if you (Think) something might happen around the next bend in the trail.

Good stuff especially the behavioral response......agreed so that said I will choose my 375 GNR #2 shooting 250 grain Hardcast FP slug at 2600 FPS short handi lever action rifle with 7 rounds.

I also think the G20 can do the job in that running high stress defensive handgun drills I am very accurate with the G20. Heck I once turned back a mother black bear who had bluff charged me 4 times with water bottle and squirt to the face at 7 feet. Notice I said bluff charge or I may not be typing this........

Have any of you ballistic "experts" read about a lil Indian girl named Bella Twin?

"Bella Twin, an Indian girl, and her friend Dave Auger were hunting grouse near Lesser Slave Lake in northern Alberta. The only gun they had was Bella's single-shot bolt-action .22 Rimfire rifle. They were walking a cutline that had been made for oil exploration when they saw a large grizzly following the same survey line toward them. If they ran, the bear would probably notice them and might chase, so they quietly sat down on a brush pile and hoped that the bear would pass by without trouble. But the bear came much too close, and when the big boar was only a few yards away, Bella Twin shot him in the side of the head with a .22 Long cartridge. The bear dropped, kicked and then lay still. Taking no chances, Bella went up close and fired all of the cartridges she had, seven or eight .22 Longs, into the bear's head. That bear, killed in 1953, was the world-record grizzly for several years and is still high in the records today. "

So a 22LONG killed a WORLD RECORD grizz back in 1953... its the old adage not so much WHAT you use as HOW you use it.

I personally would prefer a 12G. But you can bet your last $$ my Glock 10MM will be there too.
