Title: 300 win mag vs. grizz.......?
Post by: nickelstick on January 19, 2008, 11:15:22 AM
I am purchasing vangaurd sumaoa stainless in 300 win mag.  I know about the 300 on caribou,moose,sheep wolves, goats, deer, but my question is..........
Is the 300 winmag poor, fair, good or excellent on grizz/brown bears?

As with any other caliber, shot placement is the key.  The 300 win mag has more than enough velocity and energy to drop a grizzly in its tracks.

personally, i would say the .300 Winny is marginal for Grizzly but just on the right side of the margin.  I'd feel better with a .300 Weatherby and better still with a .340....especially if there's a chance encounter with a big Brown bear.  200 grain premium bullet with the .300 and 250 grains with the .340.

I agree at some point (after the wife forgets about a $1100 gun with a $1300 scope) I will probably buy a .375
I see that a lot of interior guys bust griz with 300 winmags all the time.....Probable to small for brownie........but well place 300 should rip his life out, whatcha think?

I don't speak from experience, but I've done a bit of book/online research on this, and I'd agree with JB257460. The word I would use for a 300 WBY is "adequate." As he said, a .340 is probably a better choice. If you go with the .300 Win., load it heavy and aim well.

Post by: nickelstick on January 31, 2008, 06:57:32 AM
I contacted a significant and reputable outfitter that has a brown bear reputation. I poised the question 300 win good for griz but to small for brownie's?  His response was excellent for brownie's hit proper, with heavy high grade bullet= no problem.
I think as a primary Alaska rifle 300 win mag......someday get a dedicated bear gun.  Most Alaskan's I chatted with (online) say I will fall in love with the winmag and not want anything else.  I'm getting an ior 3x18 scope, pricey but nicey.

Sure the 300 Win Mag will easily do the trick on any bear or big cat on this planet, I don't want to sound like a broken record but shot placement is the real key. I used a 300wsm on a alaskan brown bear and it was an immediate kill at 200 yards.  However, if you want to purchase another rifle, I have always found that I can somehow justify some kind of reason to add it to the collection.

Yes you can but why?  For grizz go for a 340 and a heavy for caliber  premium bullet.  Grizz are large powerful, heavly muscled, dense tissued, big boned, and very tough. An enraged grizz can cover 100 yards in about 5 seconds with his lungs full of blood and running dead on his feet.  If you do not anchor him on the first shot he may go down, he may not. If he does go down when he gets back up he will be running in what ever direction his nose is pointing. If that direction is your direction you are now in deep kimchee my son. It will be at that precise moment in time that you will  wish you had a bigger gun in your hand instead of your johnson.  If he runs into the thick, now you got to have your marlbourgh moment and then go in and get em.  You do not want to do that. This is where things get real intense real fast. It is now time to break out the automatic 12 guage shotguns loaded with magnum slugs with short rifled barrels. Scoped rifles are  useless in the thick alder and devils club. Keep in mind if he is not dead he is back tracking you with one thought in mind, to kill you.

Well said!  Anyone up for a little rabbit hunting instead?  ;D ;D  I agree with the .340 and that's exactly what I would use.  There's no better match for the .340 than a 250 grain Partition.  Remember, even though Grizzly, Brown, and Polar Bears are not the Big 5 in the African sense, they certainly are dangerous game and are the planets largest land dwelling carnivore.  Polar will hunt you with a purpose.  Humans, by the way, are made of meat  ;)

I would like to add to the previous post. Grizz are not in the big African big game 5, but they are arguably among the smartest, toughest , and most dangerous critters on planet earth.  You better be able to ring the bell every time at 200 yards off hand. Those that advocate hunting them with anything lighter than a 338 mag are putting themselves and their hunting partner in danger. Thats my story and I am sticken to it.

I got charged twice yesterday by a sub-adult who was being,as they say, a "hooligan"! :o  On the first charge the bear covered about 120 yds. in about 6-8 sec. They look like a small car coming at you! On the second charge it ran through some very heavy underbrush and over a lot of deadfall as if nothing was there at all.  The first charge he stopped at about 20 yds., then came about 5 yds. closer in 3 bounds. The second charge he stopped about 10 ft.! away. He woofed,snorted and flaired his lips and nostrils. I was wishing I had a 12 gauge with 2 rds. of O buck and a magazine of slugs! All I had was a can of pepper spray and a trekking pole. This is my tenth and most aggressive encounter so far. They are huge, fast, agile creatures.

The 300 win mag can kill a grizzly.180 will do the trick.You bust be on the money with your shot.At 100 yards the 300 win mag is moving 2,866 fps.And the hit power of 3,284 ft-lb. It will go right threw.You must hit the hart first shot.Just hitting it in the lungs will just piss it off.

Wow, this has been busy! Thanks for all the input, good stuff too. I agree Brownies deserve own weapon.
So what caliber (must be available in a Weatherby rifle) would you consider as excellent brown bear fodder? I like the idea of needing 2 weatherbys!
 Me thinks 375 H&H Magnum

Lots of hot stove talk about shooting big bears...but how much experience?

Funny, my dad spent time in the far north in the '50's, and felt that a 30-06 with 220 grain bullets was more than enough gun to take polar bears, which he did on more than one occasion.  The average male goes about 9 feet and 900 pounds - just as big as their brown cousins.  He also shot wood bison in the Fort Smith area, and the '06 did the trick on them, too.  Anyone using a .300 Win. Mag. with a heavy (200 gr. +) slug shouldn't feel undergunned, especially with the quality bullets we have these days.

That being said, if I was going bear hunting, I'd use my .338 Win. Mag., because I happen to own one.  But I wouldn't feel undergunned with my pre-64 M70 30-06 if I happened across a grizz in the pursuit of moose.  A distinct possibility where I live.

I have no experience hunting Grizzly or Brown bear.  If I spotted a big brown who wasn't aware of my presence and was simply loafing or feeding, I would probably take a shot at one with any reasonably large caliber with a bullet of high sectional density with enough velocity to get it through the animal regardless of angle.  However, if things turned bad, I'd want as big of a hole in the end of my muzzle as I can adequately handle.  A .30 caliber will definitely work in the first situation but, in my mind, a .338 and larger is called for in the second.  I'd rather be prepared for the second situation.  A .340 is tough to beat.

Of of the greatest hunters of all-time, Jack O'Connor, talks of taking grizzly with his .270 Win and .30-06.  Having said that, I personally would want a use my .338 Win Mag as a starting caliber.  I know of a excellent guide service in Alaska noted for taking trophy bears that requires a minimum of a .375 H & H Magnum.  They have a hunting video out where some clients are using calibers as big as the .458 Lott.  I know that the guides that work for this service carry the .458 Win Mag.  As JB257460 said, I would want to be prepared if the situation turned bad.   The grizzly's scientific name isn't Ursus Horribilis, the horrible bear for nothing!

Take a look at the Alaska Outdoor Directory Forum. Its full of real Alaskians talking about what they hunt and what they hunt with. 300 no problem most of them use 30 cals. one guys even talks about doing it routinely with a 270. Animals are not blood thirsty armour plated monsters, before we had magnums we had patch and ball and sticks with sharp stones before that. They all worked. JMO.

 :o  I had a few encounters with bears charging me and it is a pretty scary deal my son.  Everyone says shot placement is key here but when that bear decides to charge you, you may have only a split second to make that shot count.  I've seen a deer run off a couple hundred yards even after being shot through the heart.  So a bear shot through the heart would most likely run even farther untill it died.  Where I come from people have been attacked by bears and I heard a bear was shot like 10 times by 3 hunters, one using a 7mm, one using a 30-06 and a 243 and the bear was still able to get to them and cause some damage.  One of the hunters was busted up pretty bad, the bear actaully tossed him like a rag doll.  Thank god they made it out alive. 

On the other hand i've of heard of people killing brown bears with small calibers like .22 or 30 -30 cal but I wouldn't recomend that.  I just bought a .300 win mag for bear protection because of my few encounters, luckly I haven't had to shoot one.  Most of the time the bears are more scared of you and will only do a bluff charge.  I am pretty confident in my .300 Win mag that it will do its job if that time ever comes.

I got it today and man am I pumped!¬  The test target measured 5/8" outside to outside of lead marks, minus 1/3 equals .29 moa!!!!¬  Did I do that right 5/8 od minus1/3 (30 caliber) converted 7/24 to decimal =0.29......a dime covers everything!¬  Thanks Ed.

p.s 300 winmag for everything in Alaska EXCEPT brown bears... they deserve my next weatherby! :o ;D :D :o

one thing to remember Jack O'connor (gentilemen stand up and remove your hats) never took his 270 as a primary grizzly gun, but used a tough bullet when he was sheep hunting in grizz country that if a shot presented itself he was covered. and yes the 300 win mag is most suitable for grizz, providing you use a good bullet. I would prefer a 375 HH but would not feel under gunned if I found ole man griz and all I had in hand was my 300 winnie. I fully understand guides using 458's , 375's and what not the difference is they are carrying the artillary for a wounded bear who has massive amounts of adrenalin rushing through his body. typically the hunter's first shot is going to be at a calm bear. 
Look how many alaskans have used the good ole ought six.

If you want to play it safe get a 338 win. mag. 300 gr. will take it's head apart if you got stuck in a binde. I have been black bear hunting for 20 years and for 15 of them years I have been stuck using a 12 gauge to take them down.Here in New York state rifle just openned up in the past 5 years.The best and only way to hunt a black bear was to get him to hunt you.You want to talk about shitting your self?Do not try this with a Grizzly.
You crap in a 5 galon bucket and hang it from a tree,When that bear gets a wiff of you he will be comen for you.He's not just going to be on your path,he is hunting you.
Last year I took 645lb.Black bear with my 300 win.mag. and what a mess I made of him.Over kill!! His heart and lug blow apart. Every one under estmates the 300 win.mag.
It's range is 1,000 yards. It will hit at 500 yards with 1,950 ft.lbs. That will go right threw a grizzly's head.But you don't want to be staring face to face with a grizzly and only have the 300 at hand.So when I go the my uncles in Canada I will be bringing my Browning B A R 338 win.mag. If the first shot don't do it,I have 4 more at a squeez of a trigger.

I've seen a grizz dig a trench the size of something a backhoe would produce after being shot through the heart at 150 yards. So, considering the will to live these giants have, even after being mortally wounded, the best thing to do is try and put some distance between you and the bear. Last year a hunter was killed by a grizz near Sundrie, Alberta, Canada, by a grizz. When they found his body a round had been fired from his rifle. So it looks pretty bad no matter what you do when caught to close to a grizz in the bush. It might take some of the clever wits we get supplied with to survive such a surprise meeting with one of the most powerful and well equipped land animals on earth. So not only the size or caliber of gun is important but also how fast you can empty the clip and reload might come into play. Another reason as many hours at the range refining the use and feel of you rifle is important.
Good question but forever tough one to answer.

Cheerz!

At 150 yards, probably excellent with heavy bullet and proper shot placement, however; at 30 yards POOR, because if the shot fails to break the spine, your going to have the bear in your lap in about 2 seconds, .... it won't be happy and even if heart shot, it's apt to have at least 2-3 minutes of life left! Odds are it can shred any man, in less than 20 seconds, if in a bestial rage, generated by pain. While in ALASKA,(11/77-05/79), I came upon a scene,(still wet), where a black bear and grizzly WENT A ROUND. The black bear,(over 300 lbs), was torn up,.....unbelieveably. I believe that most of us HOPE to get a shot at one, at some DISTANCE, but; ask yourself if your rifle of choice will hold up to a charge at 15 ft. I have a .416 Rigby,........and if I went for Grizzly/Browns;.....I'd use it; and NO ONE could give me an arguement that would make me sorry I was carrying it!

I`ll agree with bigger is better. My thinking is a good caliber for both,a distance shot and close up dangerous situations. A .340 would do nicely at that "job",.375 H&H,better still. We always joked about carrying a .44 mag backup revolver,first 5 shots for the bear,last one so I don`t watch myself eaten alive. :)

As much as I enjoy my pre-64 300 Win Mag.
I respect it's limitations. It has served me well as a deer, elk and caribou rifle.
When it come to the big bears, be it inland or costal grizzles, I much prefer a
medium bore rifle. I have shot the 340 Wby for several decades and trust it to
do most jobs at hand. With that being said, if I were going to invest in an adventure
of a life time, I would want the odds in my favor as much as possible. The perfect
shot is a seldom thing in the real world. The 375 Wby looks mighty good as an all
around rifle chambering to me.

Just on a side note, from having lived and worked in bear country...
Bears both large and small, have my full respect. Pictured below is my saddle carbine
that rides under my leg when a horseback in the tall and uncut. Fast and handy to have in camp as well.

Years ago when Montana sold grizzly licenses, I would buy one every year and I had no qualms about hunting them with my .30 Gibbs and 180 grain Partitions.  Unfortunately I never saw a bear to shoot.

Also many years ago a hunter in NW Montana mistakenly shot a grizzly with his .30-06.  The bear ran off and the next spring MFWP live trapped that grizzly and found the bullet just under the bear's skin.  The bullet went through the bear's chest, and he completely recovered.

This fall I'm booked on a western Alaska brown bear and moose hunt.   I'll be using my .375 RUM and hopefully 270 grain Barnes TSX bullets...IF I CAN FIND SOME MORE.

If I ever hunt grizzly bear's again, my first choice rifle will be my .300 Weatherby with 180 grain Barnes TTSX bullets.

A few years back I went to Kodak island with a co worker to hunt Sitka black tails. He took his 300 weatherby loaded with 190 bergers. I had a 300 win mag stoked full of 210 Bergers. We got our deer they took both rounds to the boilers and stayed on their feet. On the third day we went to recover 2 deer that a fellow hunter had downed the day before and left over night. He stashed them in the alders and I wished I had loaded up some 220 partition instead of bergers. Both deer were fine but after the amount of punishment the deer took on that island I wonít be taking bergers again. We never did see a bear but the 3 other boats in that bay were looking for the 9íplus boar that had been seen in the area. Shot placement and bullet selection are key. Choose wisely.
