Home Forums Hunting & Shooting General Big Game 300 win mag or 7 rem mag

I’ve killed big game with the .223, 7mm Rem Mag, .300 WSM and .300 Win Mag.

I personally find the recoil difference between the 7RM and .300 Win insignificant. The .300 is more but it doesn’t bother me. It just feels different. The .300 WSM is more like the 7mm recoil wise.

I’ve killed the most game with a 7mm Rem Mag followed closely by the .30-06. If I were you I’d shoot them in similar rifles and see what your opinion is. Around here there is far more 7mm components than .30 cal in these times. I’d shoot a .300 with 180s if it was me hunting those things. Maybe 200’s if I did more Moose and Elk. 180 grain .30 caliber bullets at 3,000 FPS will be plenty for anything on your list.

? ? ? ? ?

How many 7 RMs & 300 WMs have you loaded ?

Yes by comparing cherries to apples you can get 20 or more grains diff BUT
that ain't normal.


From Nosler # 7 manual

7 RM - 160 gr bullet Mag Pro -- 72 grs Max load

300 W 180 gr bullet IMR 7828 - 70 grs Max load

* My 8 RM 200gr IMR 4831 - 80 grs Max load -- Re JRS

REALLY ?

All grains matter

I have both a 7Mag and a .300 Win. Have used both over the years to the point of which rifle killed what.? Overall I cant say that I noticed any difference in killing speed between the two.

I Used mostly 180 & 200 gr in the .300 and mostly 175 in the 7.

Moose, Caribou, deer, elk, grizzly bear all taken cleanly. Never lost a animal with either. Recoil with the Win a little sharper.


BTW my .308 kills as good as the .300 and 7.............

I’ve loaded for both a lot and for a long time. it just depends on what bullets you’re using and what powder and gun. For years a 160 nosler partition with IMR or H 4831 was 62 to 65 grs depending on the gun. At the time I was shooting 83.5 grs of h1000 out of a 300 fed 215 m and 180 sbt and you could run 80 with 200s by the book Talk about cherry-picking. I believe I said about but you want to cut me over a grain or two GFY. And just in case you can’t figure it out for yourself it was said with humor.

The 35 whelen shoots far enough....

If you have a 1:8 twist barrel, the new Barnes Bullets, 208 gr LRX will be a great hammer. Have been shooting it in my new 24" 300 WM with Peterson brass and have been getting .5" and .6", 5-shot groups with Rel 26. Not sure what info is out there yet but i've been given permission to talk about it.

I’ve mostly gotten over the .300___ virus, find that game doesn’t fall noticeably quicker with them than with the .30-06 or .270 and the right bullets.

In the 30-06, with a 200 gr Nosler Partition going 2730 fps in an accurate rifle, I don’t lack for hitting ability within what I consider maximum range (500 yards).

I have similar feelings about the 7mm Rem Mag and the .270. I load a 150 gr Nosler Partition to 3050 fps, get excellent penetration (pass throughs) on elk with a lot less fuss and a lighter rifle. And if I want even more penetration, I will use the 160 NP at around 2800 fps.

If I want more power, next step is the .375 H&H for me.

Boring, but there it is. The bullet is a lot more important than the caliber.

That sounds pretty wicked.

Will that seat in a standard 300 Win chamber or does it need to be loaded longer?

I’ve shot a bunch of elk with a 300wby and have seen a bunch shot with a 300win. I’ve also shot a number elk with a 7STW using 160 accubonds. My hunting was in country where shots averaged 350yds or more. I also have a strong preference for breaking an animal down on quartering shots by taking out at least one shoulder (I know a lot of folks do not share this view). All killed efficiently. I tend to load rifles for using a single load for deer and elk. Comparing the 300s with the STW, I d be shooting 180/200s vs 160s in the big 7. For elk and moose, I’d always prefer the heavier .308 options. To be clear, There is not an elk or moose alive that could take a well placed 160accubond out of any 7mm cartridge. It’s just at the ranges I hunted, I felt the extra weight was more likely to hit harder and leave two holes even if a shoulder was hit. FWIW, my elk cartridge of choice is a 340wby...which also kills deer plenty well.

What rifle, and what do you shoot outta that?

My .340 Accumark loves the 225gr TTSXs loaded by CorBon, and 3,140 fps outa the muzzle.

Mark V synthetic. My preferred load was the factory 210 partitions at 3250. It would regularly clover leaf and accounted for my longest shots on deer and antelope. Sadly, Weatherby no longer makes these loads and I’ve been unable to match accuracy and velocity at the the same time. I’m presently playing with 225 accubonds and partitions using RL26. I’m making progress but not done tweaking COAL. They’ll shoot well enough....but not what I’ve come to expect from the rifle.

Shoot like this at 100 yds out of mine:



Might want to give them a try.

Work well on moose too:

Pretty hard to beat a 300 Mag for all around mixed bag hunting especially from sheep to moose.
I’ve had great results using 200 Grain Nosler Partitions . Nothing wrong in choosing the 7mm Mag either.

Yes both great cartridges!

The .340 Wea Mag is a real killer. It was my cartridge of choice for elk and moose when I was younger. I used 250 grain Nosler Partitions @2900 FPS exclusively. Both rifles I had were very accurate. One was a custom on a post 64 CRF win Mod 70 Echols Legend stock and the other a Dakota Arms Safari Grade both with 25” barrels. Both .340’s weighed around 10 1/2 lbs with their 30mm 1.5-6X42 mm scopes. Now for elk , moose and larger antelope I user lighter weight 300 Mags, they are lighter and recoil less.

Recoil is a funny thing. My 300wby and 340wby had identical factory stocks. I much preferred the recoil of the 340—it was more of a heavy push.
