Home Forums Hunting & Shooting Ask The Gunwriters .264 WM vs 7mm Rem Mag

You're right, it's all a marketing conspiracy. The fact that the 7mm RUM has considerably more powder capacity than the 7mm STW has nothing to do with it.

Mule Deer,don't take it wrong,but Remington does seem to hype things up when they introduce things sometimes.Remember the introduction of the 7mm Express.Here is some good info on the 264 Win Mag,7 Rem Mag,7mm STW and the 7 RUM

Nice looking Sako's, probably accurate too. The first accurate .264 mag I was around was a Sako! Back in the day (60s & 70s) the pre 64 M70 Westerners I was around didn't seem very accurate, Then later in the 90s I bought one for a donor and had PacNor rebarrel it into a 7 RM, then it was a fine rifle.

Don't forget the lawyers and bean counter conspirators. They take all the fun out of reloading.

I always figured velocity potential was roughly proportional to sectional density in a case with a given capacity. For example, a .25-06 will drive a bullet to the same velocity as a .270 will, given equivalent sectional densities of the bullets used in each. They'd likely require different powders to make it happen, though. In comparing .270 to .280, though, there's not enough difference in bore diameter to make powder choice a significant factor.

I could never get to 3100/160 in any 7mm Rem Mag (24") "until" I used a 26" barrel and R26. R33/175NP got to an easy 3030fps. I like the "idea" of the .264WM, I have a good friend who has used the same, 24" Mod 700 since 1979. He usually shoots factory 140 clkt...a 24" .270 is probably going faster, ha, but he has killed " a huge pile" of deer/hogs with it. I "want" a Weatherby 6.5 RPM!!!

Accuracy node with 150g with R#25, WLRM is at 3200-3250

Accuracy node with 160-162g with Retumbo, Fed 215 is 3100

All 26" Rem 700 factory barrels

Small groups abound, and we use Gentry muzzle breaks

Oh NO! now you’ve gone and done it ! !
Man, where U been ? Don’t you know the 280 is far superior to the 270 ?

Now you’ll be vanquished from the ‘fire’. Sorry.


Some won’t admit the CLOSENESS of those 2 cartridges.

I’ve long said, if you have a 270 you have a 280 and Vice Versa.
Now we both gotta duck !!

Of course I do! I just don't like to rub it in...

If the 280 is manly and the 270 is metro where does that leave the .264? Singing falsetto in the locker room?

280 —> Chuck Norris
270 —> Tom Cruise
264 —> George Michael

baldhunter,

I wondered where you came up with some of your notions. Unfortunately, while ballisticstudies.com is interesting, it's not the entire body of knowledge on ballistics--especially his notion that it's impossible to get any more velocity from 7mm bullets than can be produced with the 7mm STW. That sort of idea is simply not true, especially since more progressive-burning powders keep appearing.

You might want to check out recent data, such as the latest Hornady and Speer manuals, both published in the past couple of years. Both list the 7mm STW and 7mm RUM, and both happen to use the same barrel lengths for both rounds, 26" in the Hornady and 24" in the Speer. With 160-grain bullets (traditionally considered the best all-around weight for 7mm magnums) the RUM beats the STW by 150-200 fps. Which it should since it has more powder room.

Fixed it for ya.

I'm happy being Chuck Norris!

280AI = Arnold Schwarzenegger "I think that gay marriage should be between a man and a woman." Not sure what that means?

My favorites, in order;

.264 - Sugar Ray Robinson
.277 - Rocky Marciano
.284 - Sugar Ray Leonard
.257 - Roberto Duran
.308 - Joe Lewis
.338 - George Foreman

We have killed bull elk side by side , .264 and the .270 with the same bullet and no appreciable difference. The .264 win is one of the best 6.5's ever. The problem with it and most of the belted .284' s is their need of a long barrel. That is the deal breaker, a 22" barrel/ repeating rifle is my criteria. This is where the .270, 280 7/08 and their like shine,imo

..... and standing in the shower!

Like many a young man, I did not fully appreciate how smart my Dad was. A couple of years before we moved to Alaska Dad bought a new old Mod. 70 Westerner in .264 Win. Mag. with the slender 26 inch barrel. He used it for mule deer and antelope in Montana and Wyoming and on fox during the Iowa winters.

When we came to Alaska in 1965 he brought his .264 and a pre 64 in .375 H&H, a .300 Savage Mod. 99 and a fixed up Springfield 03A3 ought six. I used the ought six and Dad stuck with the .264 Winny and 140 grain Partitions driven by a case full of surplus H4831. Dad had complete faith in the rifle and load and that was that. He could see no use for any thing bigger. But, he did say even though he knew he could take a big bear with the .264 the ought six or .375 were better suited for the task at close quarters.

Where does it end and begin with the .264. the .270. the 280, the .284, etc. That's with out all the different case dimensions to factor in. Ya got me, and with the right bullet in the right place at the right impact velocity and depending on whether the critter is inhaling or exhaling and how tough that individual critter is compared to others of it's species, only the critter knows!

If one runs into the "Chuck Norris" of a critter species then all bets are off, I mean why else do we carry extra ammo, ain't because we ever miss or get poor shot placement!

You said it ALL, right there. The headstamp doesn't do jackshit.
