Home Forums Hunting & Shooting Hunting Rifles Practically speaking is there anything a 300 WBY Mag can do that a 7 Rem Mag can't?

Yes, but the extra punch from the .300 is largely wasted energy until you get into the big or bad stuff.

Yup. I'll admit here on the fire that I do miss,quite often.


With the Norma brass,I would've added more powder till it equaled the other load.

Surely, but the wrong bullet in the right rifle is still wrong. Either way, in the OP's case, I say shoot what you like, like what you shoot. If you've got a pile of components, and like shooting rig "A", there's little doubt you'll suffer.

Whichever rig "A" is....

Not being sarcastic: That's what I've been expecting someone to say.

PROBLEM - 62 grs Surplus 4831 = NO ROOM for any more powder, full case, compressed load.

Those cases WERE the problem, don't know how- if they were thinner, weighing less, there should have been more room, there wasn't.


Just 1 of those things. Stuff happens; I wouldn't have had any idea IF I had not chronoed those loads. I didn't have any suspicions, just chronoed "just cause".

Of course!

And, let's not forget that you can load a 175 gr bullet in the 7 Rem Mag to within 50-75 fps or so of the velocity of that 140 gr in the 270 (2900-2950 fps or so).

This will hold true pretty much across the caliber spectrum of magnum cases vs standard.

Advantage? Some think so;especially on heavy game and as distances increase.

Last year I lost my first big game animal, a cow elk I shot at 400 yards with my 7mm RM and a 165g North Fork SS.

The problem wasn't the cartridge, the rifle or the bullet. The blood trail started out as the largest I have ever seen with several thick ribbons of black blood a good 2 to 2-1/2 feet long and about 3" wide. Evidence from brush along the trail showed I hit it high, below the spine, with an exit. The color of the blood suggested a liver hit, further back than intended. The blood trail kept getting less and less and in the end I was tying orange flags at every tiny drop we could find, maybe every 30 -40 feet or so. While we initially expected to find the cow down behind the next bush, then the next and so on, it went over two ridges and escaped to private land.

Is there some larger, more powerful cartridge, but still smaller than a 105mm howitzer round, that would have increased the damage done and resulted in a recovery of the elk? Would a .300WBY have done the job? Perhaps, but I have my doubts. Maybe a .338, 9.3 or .375 of some flavor? Maybe a .416, .458 or .577?

Unfortunately no one can ever know. What I do know is the 7mm RM performed flawlessly for 30+ years and has taken more elk than all my other rifles combined. Better placement would have resulted the same straight-down results the 7mm RM produced many times before and many other placements would have resulted in a recovery at some distance. In any case, I don't blame the 7mm RM and have enough confidence in the North Fork bullets that this year I'll be using a 140g NF SS in my .280 Rem.

It's a sickening feeling no matter how many Xs you re-live it.
I certainly don't like it but it happens IF you hunt long enuff and shoot enuff animals. STUFF happens.

I agree with your assessment. "The problem wasn't the cartridge, the rifle, or the bullet."

ONCE - I had a bullet deflected >>> horrible story. Many yrs. ago. I remember every detail.

I had a friend who hit a deer in the nose....found its tongue! He hasn't forgotten either. ( I wasn't with him and don't know why/how)

Jerry

Did you try a different powder?

EHNM -

"Did you try a different powder?"

Seriously, why?

Those same components produced 3100 +fps in OTHER brass.
I actually used those same lots of powder/primer/bullets in other brass and BINGO.


Seemed conclusive to me - THAT brass was funky.

Tell me what/why other powder would have done better.

I'm not being sarcastic/hateful or humorous.

Jerry

And that's why I have a .300 Wby. I also have a 7mm rem. too. Each has a different purpose. I'm not really into the long range thing for its own sake but I do trust my .300 will do its part if I do mine close or far. It's noticably more effect on larger game.

I think that's true.

But what I notice is that a properly applied bullet from either one, puts animals under the knife.


For the record...two of the fastest kills I've seen on 6x6 bull elk,were with a 7 Rem Mag and 160 gr Nosler Partitions. One at over 500 yards.

I suppose I have commented on this before.. My choice would be the .300.. Heavier bullets and more punch.. But there are no flies on the big 7's either.. Have a Rem. and a 700 with a 7mm Wea. barrel on it.. Have killed alot of game with both, but I still like the .30's best.. The 7mm Rem. was my late wife's big game rifle for the last 15 years she hunted.. She made some awesome shots with it simply because it shoots flat, and hits hard.. I guess it is pure personal choice..

This is sorta why I went with the 7mm Mashburn Super. Splits the difference between the 7mm Rem and 300 Wby. The Mashburn runs 160's at 3200 (similar to 180's at 3200 from our Weatherby) and 175's at 3050-3075 (similar to the 200's at 3050 from the 300 Weatherby). So far the Mashburn has been really easy to shoot in a 8.5lb rifle, where as the 300 Wby wouldn't be comfortable without the brake on it, for me.

I like them all, but as someone keeps telling me, I don't need the 300's since I have the Mashburn.. They are probably right, but I am hard headed sometimes..

Let's think about this for a second.... You don't need a 300 magnum because you have a 7mm mashburn and a damn good 338 win mag.... The 300 is like a 3rd wheel in your case....

nothing it can do that a 7mm 175 gr Partition can't do just as well
