For all you hair splitters out there which of the following rounds has the best performance and most potential?

7mm Rem Express
280 Rem
7x64mm

and how would you say they rate up against the 284 Win?

Well the 280 and 7mm express are the same round.

The 7x64 case and 280 for all practical purposes have the same capacity.

I won't attempt to split hairs that fine.

Ah rich, now you are trolling.

Yup!

Don't know anything about the 7X64 other than its dimensions , but the 284 win case has almost identical capacity to the 06 case thus the 284 and the 280 are "ballistic twins."

I just knew there'd be a place for this Graemlin.....

Exactly right.

280 vrs the 284. Not exacltly ballistic twins, close but this is load specific. With a 140-150 gr bullet there isn't much difference, and I would say if your into light bullets, the 284 might even come out a little ahead in 130 gr bullets do to its design.

Where the 284 starts choking is with heavy 7mm bullets, 160 and 175 gr bullets, pushing those long projectiles into the case, reduces powder volume.

There are some tricks that can be done with the 284, long throat the chamber, this evens out the playing field somewhat. Down side is unless your building a 284, using a long mag box, this won't work well on most factory rifles, simply the rounds are too long for the magazines.

The other downside is if you set your custom that way and decide to shoot 140-150 gr bullets the bullets are seated away from the lands too much for me. Another downside is the 284 conversion is rail work on a custom build, using most bolt actions, just extra cost.

Other than the samll quirky differences noted above, the two rounds are two peas in a pod almost. I am of a mind that I like 284 Win in rifles built that way, like some of the levers and auto's like the Win Model 88's, Model 100's, Browning BLR's and even Savages. For a bolt action rifle the 280 Rem is more practical. Certainly not a performance issue more a what the rifle was designed for point.

The 280 and the 7mm Express was Remington screwing around with marketing nonsense. The 7mm express to 280 loads were supposed to bring up the pressure a tad, and give a little better performance. Unfortunatly it was all Remington marketing hype, the actual ammo over the chrono said differently, if anything it went down by 20-30 fps.

Remington has screwed the pooch on the 280 for years, its almost a text book case on how to make a cartridge fail. First intially chambr it in a trombone, hold thhe pressures down to accomidate that design. Then rename it 3 times ( 280 to 7mm Express to 7mm-06 back to 280 ), and finally quite chambering it anything but the least intersting rifles in your lineup. Sounds like a recipe for success to me.

The 280 and the 7x64 are pretty much the same thing load data is even interchagable. Norma makes some of the best factory ammo in my opinion, Federal has brought out the new HE loads for the 280, and finally there is some US made ammo that brings out the capability of the 280.

The .280 rem is one of my favorite calibers. There is no point in comparing it with the .284 win. Not enough ballistic difference to count. Just your preference.

Gee, I dunno...

I'd guess the differences are similar to those between:

-The .250 Savage and the .250-3000, or
- the 6m/m Remington and the .244, or
-the 6.5/.308 and the 260 Remington, or possibly
-the .280 Ross and the .280 Kynoch, or
-the 10.75x73 and the .404 Jeffrey, or, or , or, (how far do we want to take this?)

Well, cheewowah! The 7mm Express Remington and the .280 Remington are identical, so neither is better. Rem. handicapped both by chambering them in their semi-autos, necessitating underloading of factory ammo!!

And, if you go by case capacity alone, the .280/7mm Express Rem. has a longer head-to-shoulder length, and consequently, a very tiny bit more internal space, than the 7X64mm. Therefore, the .280 is "better". But actually, there isn't a dime's worth of difference between them!

Now, as to the .284 Win. It has about the same potential and ballisic perfomance with light bullets as the others but has limitations with heavy bullets, due to the long bullet encroaching on the powder space. However, the short-fat .284 case has a lot of accuracy potential!!

MOST wildcats based on the .284, as well as the .284 itself, are a little more accurate than comparable rounds based on the .30/'06 case!

Id argue that one all day long !
Do you want to buy a 45/70 improved ?

If you could only have one centerfire rifle...I'd pick one of them!! I do like the 6.5x06 AI a little better. Animals on the receiving end won't know the difference!!
