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.

Here is a pair of junkie old 264’s. I think a 270 Weatherby is a bit better also. 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.

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 just never could get myself to buy a 264 Win Mag because I think the 7mag is a little better.I can get 3200fps with a 150gr Ballistic Tip,my favorite bullet for deer and 3100fps with a 160gr Accubond,another great bullet.Brass is easier to find,great selection of bullets in the 7mm and if you buy shelf ammo,prices for that is cheaper too.I have four 7mags,all are great shooters and they all will shoot the same load very well. 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

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 !! Jerry

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

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.

My favorites, in order;
.264 - Sugar Ray Robinson .277 - Rocky Marciano .284 - Sugar Ray Leonard .257 - Roberto Duran .308 - Joe Lewis .338 - George Foreman
What could be a sadder way to end a life than to die having never hunted with great dogs, good friends and your family?

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

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!
