300 win mag 180 grain barnes mrx for grizzly

[Don_Abbate]

GOT A GRIZZLY DRAW AND JUST WONDERING WHAT PEOPLE ARE SHOOTING WHEN THEY GO FOR GRIZZLY BEAR. AND IS 300 win mag 180 grain barnes mrx a good choice

[Phreddy]

That'll do the job. 200 gr Nosler partition will git 'er done as well

[Don_Abbate]

i also have 200 grain trophy bonded bear claws but the mrx has more ft/lbs of energy

[Don_Abbate]

shot placement, vitals or shoulders

[Don_Abbate]

What would be a list of things i should carry on me and in my pack to be fully prepared to go grizzly bear hunting

[Dirty]

Why are you specifically asking about a 180 MRX? Do you prefer 180 grains or the MRX bullet specifically?

I would just as soon use a 165 Grain TSX in a 300 WinMag. There are plenty of great bullets out there (Bearclaws, Partitions, Etc), but the Bartell/Gatehouse tests this year on wood blocks showed that the lighter Barnes Bullets have better penetration and just as good a wound channel as some of the heavier bullets from other manufacturers.

[Don_Abbate]

more the mrx bullet

[Dirty]

Why the MRX? Do you plan on sniping your bear from a long distance? :lol:

[Don_Abbate]

nope i just heard good things on the penetration of the bullet

[Gateholio]

If I was taking a .300 after grizzly bears, I would probably choose a 180gr TSX or 180gr TTSX. MRX woudl work fine, but they are designed for longer range shooting, and WAAY more expensive.:D

[Don_Abbate]

i bought the mrx so im gonna give them a shot if i get lucky and see a bear

[guest]

My best 300 win mag load is 71 gr. 4831 IMR and 200 Gr. Nosler Partitions
Brought down every thing it's hit so far.
Better group from this then the 180's.

[elkhunter1]

What do You guy,s think about 338 Win Mag 225 grain Hornady
for Griz.??

[Gateholio]

i bought the mrx so im gonna give them a shot if i get lucky and see a bear

They shoudl work fine:D

[Gateholio]

What do You guy,s think about 338 Win Mag 225 grain Hornady
for Griz.??

Should work finr, but if you want, you can use a better bullet or a 250gr Hornady.

[Will]

300 win mag is too small for grizzlies.......bring lots of shells:neutral:

[Fisher-Dude]

These guys will tell you to get rid of your 300 and buy a 25-06.

[Ruger4]

Don your selection will work just fine for grizz

"300 winmag not enough" ???
Will, you need to practice more ..... ;-)

[chilcotin hillbilly]

Don your selection will do just fine unless you are hunting grizzly in Clearwater then you will need a 458 Lott as a minimum.:-o

[srupp]

The rifle is fine..I am not sure of the difference between the MRX and the TSX??
I would like a 180 TSX...however I do not know about the MRX..I shoot the .338 and the 225 TSX..

ANYONE know what the diff is with the MRX..
As I am a strong supporter of the shoulder shot so I prefer the bigger stronger 180 grain TSX???

[Bowtime]

I took down my grizz with a 30-06 165 grain. One shot dropped him. I Like the 300 mag, allows you to reach out there if need be. It's a great choice for grizz.

[uraarchr]

from what i've read the mrx has better numbers for long range ballistics and should (made to) open up better at longer ranges.tungsten core?i have one recovered from moose at about 450yds or a little more.perfect mushroom.no experience w these on bears.yet.

[dutchie]

MRX stands for "Maximum Rapid Expantion"

TSX stands for Triple Schock Expantion

TTSX stands for Tipped Triple Shock Expantion and TTSX has a better B.C. then the MRX and the TSX

With the MRX it will expand with Less energy, but it will hold up close too.

so the longer shots with less energy on impact the MRX opens up the same way as a TSX or the TTSX 300 yards or less.

If you want to learn alot about bullets call the manufacturer. Dave Card at Barnes reccomends the TTSX over the MRX for anything 300yds and under.

Dave Card is the todbartell of Barnes!

As for the 300wm for Grizz... that bear runs fast and is accurate. In my opinion there is a reason why guides say a minimum of a 338wm. But they know were the game is, not how bullets expand.

But gatehouse's experiment would take the wind out of anyones sails so I think that Gatehouse has a great point, BUT I think Will was a guide for G.Bears tho.

For saftey I would probably go with a 200gr TSX, TTSX, MRX and just keep shooting or a 338wm with a 225gr Barnes (I like Barnes)

BOWTIME - - - - YOU GOT SOME BALLS! that is a good shot but way to risky IMHO

[Brett]

MRX's have a much higher BC value almost .500 and that makes them great for long distance, less drop better in wind ect. But you have to pay for it $$

[srupp]

here we go talking long range shooting of grizzlies...hmmm sounds like advertising for another episode of BEST OF THE WEST..lol

Thanks Dutchie for the valuable insights into Barnes..I really like their bullets/

You are correct they do have a high BC, but the TTSX has a higher BC. What makes the MRX expensive is the "Silvex" core which is a tungsten based core to make the round shorter then the TSX and the TTSX.

The tungsten hits with more energy at lower velocity and it is damn expensive as all the waterfowlers know! that is why it opens up at long distances better then anything else.

The TSX and the TTSX are pure copper

BC data
TSX - .453
MRX - .473
TTSX - .483

the MRX will open up the same way as the TSX and TTSX and will retain the same weight. The only reason you would want to be shooting the MRX over the TTSX is if you are planning longer shots (+300yds). and I am not saying long range shots on Grizz, i am saying any deer, elk, moose primarily.

As for the Grizz. MRX is (waste of money for the above reasons) too much technology for a short shot but it is a perfectly good round for penitration and reliability! It will also perform exactly how you want it too.

[srupp]

exellent information.

[Will]

Will, you need to practice more .....
Yes apparently I'm lacking the firearm experience of some.....;-)

[Brett]

I hadn't looked at the ttsx data, Thanks for the info!

[Don_Abbate]

300 win mag is more then enough if you place your shot, look at all those hunters out there who hunt grizzly with a bow

[olharley guy]

Howdy all - new here I have been reading the forum for quite awhile now, lots of good information and sometimes very entertaining. LOL
I haven't hunted for a few years-since I moved to the Island after living in the Yukon for about 30 years.
We spent all our spare time in the wilderness hunting, fishing, trapping etc.
I have shot ????? Grizzlies,?????? Black bears, ?????Moose, ?????Caribou?????? Sheep?????Goats,??????Wolves etc.
As for the topic on hand, I purchased a 300 W. Mag -700BDL-Stainless barrel when I first moved up north and all game was taken with this rifle and all done with one shot except for one young bull moose which
took 3 shots at about 50 to 75 yards??
I found this to be an excellent rifle but don't ever shoot a Coyote with it, big mistake when you are trying to get enough hides to make the wife a fur coat!
I know I am a little behind the times but the only bullets that I ever used were Winchester Super-X with the 220 grain silvertips and Federal premium 180 grain bullets right off the store shelf.
They all did the job they were supposed to do even though buddies used to reload all the time, I just never got around to learning about it back then, so for me the factory loads worked just fine.
Keep up the fine discussions. Later

[todbartell]

MRX stands for "Maximum Rapid Expantion"

TSX stands for Triple Schock Expantion

TTSX stands for Tipped Triple Shock Expantion

MRX stands for maximum range X

TSX - triple shock X

TTSX - tipped triple shock X

the X bullet has been out since the late 80s in various forms, the X refers to the 4 petals, not expansion

ok back to topic

300 Win mag with a 180 TSX, TTSX, MRX = dead grizz, assuming bullet is placed well

NEXT!

[pupper]

what about 165 grain barnes tsx bullets on grizz, adequate? or go heavier with a 180grain. Still talking .300wm.

[todbartell]

165 should work well too, in an X bullet. Bullet weight isnt as important as it is with other designs. Ive put a 30 cal 165 gr X through 45" of deer lengthwise with exit, so I'd bet it'd break some grizz bones if given the chance :)

[elwood]

the bigger the bullet the better also carry a clothes pin for your nose and tide detergent if you miss when it comes running your pants could get filled goodluck

[6 K]

The one advantage the MRX has that I like is the shorter bullet length. Lead or in this case Silvex is a lot heavier than copper, thus leaving more of the case capacty for its original purpose. To hold PROPELENT:twisted:.
Most often for grizz I am a fan of the heaver bullets but, in when it comes to X family I don't expect you will lose any weight. So I'd say load those MRXs as fast as your gun will acurately shot them and punch the first one throught the exit side shoulder. After that, repeatedly hit the front half of the roaring blurry whirl wind thing that is looking to kill you:wink::shock: .
I agree with Bartell as to what the letter designation stands for.
Best of luck to all you who got drawn. I am still waiting to see what the L.E.H. fairy brings.

P.S. where did you find M.R.X.s ?

[MOWITCH SLAYER]

My best 300 win mag load is 71 gr. 4831 IMR and 200 Gr. Nosler Partitions
Brought down every thing it's hit so far.
Better group from this then the 180's.
CT
Have to agree 100% I load pritty much the same load. Just a little more 4831

[guest]

I loved the performance we were getting with 165 GR Partitions in 308 and 30/06, tried the 180 and 200 grain in the 300 Win Mag. and all is good so I have no intention of switching Bullets. If I had tons of cash and time, sure I would like to see what other Brands do but can't do it all.

I do load the IMR 4831 at 73 also with 200 partitions but I know thats pushing the max and have been happy with 71. Brought down G Bear, B Bear, Elk, Moose Sheep, Goat, Deer, yotes, so ........ can't harp about that from partitions, it's all in what your happy with, why fix some thing that AIN't broken.

It is MAINLY about placement of the shot.

Just practice lots and have a partner who can't run as fast as you for a back up gun, Your 300 is plenty, just be confident with it.

GOT A GRIZZLY DRAW AND JUST WONDERING WHAT PEOPLE ARE SHOOTING WHEN THEY GO FOR GRIZZLY BEAR. AND IS 300 win mag 180 grain barnes mrx a good choice

wheres your draw for Don?Hopefully we can help you out.300 w/180 sounds good!

[Don_Abbate]

Hey My Draw Is 6-19 Goin With 2 Other Buddies We All Got Draws. And I Got The Mrx At Italian Sporting Goods

[eaglesnester]

Yes it will however if it were me and it was my tag I would want a 200gr tsx at least in my 300. Why go with a 180gr? You got the powder and you got the power why not use it to the best advantage? You are going after a tough critter with heavy dense muscle tissue and heavy dense bone. I would go for the heaviest round I could find. I carry a 300 Weatherby Magnum and all I load are 200gr tsx for hunting for everything. If I were going for grizz with my Weatherby I would want a 220gr tsx, I am not sure if you can get em that heavy in 308 but if I could get em that heavy that's what I would load.

[todbartell]

they only make a 200 gr TSX in 30 caliber. A 220 gr would be extremely long and would require a faster twist rate than what the average 300 has (1-10 twist). Even the 200 gr TSX has a warning with it not to be used in a twist of anything slower than 10.

I would step up to a 338 caliber rather than try to max out the bullet weight in a 300. Heavier bullets in a regular style soft point will penetrate deeper than a lighter one, but that is not the case with the X bullet. Alot of people have a hard time getting around this :)

[Don_Abbate]

i might be using a 416 rem mag borrowed from a friend that should do the trick

[TherealSLYFOX]

im gonna use a 180 grain nosler for my trip to bella and if that dont work ill whip out my crossbow and finish him.

[todbartell]

i might be using a 416 rem mag borrowed from a friend that should do the trick

for sure it will, impressive cartridge to say the least! I used to own one, shot a moose and deer with it (and a coyote :razz:)

since you wont be super familiar with it though, you should do alot of practice with it in the next couple months before the hunt. Ammo is ridiculously expensive, which inhibits the practice needed.

Brute force of a 350-400 grain bullet is nice, but shot placement is what counts. Your 300 Mag is more likely a better choice for you right now.

my .02!

[Don_Abbate]

yah i am more comfortable with the 300 at the end of the day im just going to bring the 300 well have 3 300's aiming just incase so it should be fun
