7x57 verses the 284 Win.

Which one is better and why!

yawn!!!

Does one have to be better ?
I think the .284 has a little more room for powder, so you can probably get more velocity with it.
But I like the 7X57. I like it alot !
Can't say its better than the .284. Or the .280 or the 7mm08.
They are all prety much interchangable. Take your pick.

The 284's way more accurate, you illiterate or sumthin?

Both good,but,for me......neither.280

I'm going with a wildcat - the 7mm x 257 Bob <g>

Just for conversation's sake , does anyone know/have handy the case capacities of the 7-08, 7X57, 7X57AI, and 284? IIRC Mule Deer wrote an article with a table that listed a bunch of 7mm case capacities, but I can't seen to locate it.

Can U please rephrase your question. I seem to have a lot of difficulty comprehending what u'r looking for...LMAO

All case capacities are approximate, because brass varies, but with a typical 140 spitzer loaded to factory OAL here's a close enough list:

7mm-08 50 grs.
7x57 53 grs.
7x57 AI 56 grs.
.284 59 grs.

Here's the deal on that. A 284 loaded to factory OAL is not going to get much over a 7-08 especially with the longer bullets. A Wyatt's box or a winnie short action allows a longer length and can get 'er to really purr along, without any pressure issues. I think Melvin uses a 3" box on his NULA. My 284 on a M-70 can get closer to a 7wsm than a 7-08 can get to the 284. I own all three. It very satisfactorily fills that gap. I would also think the 7x57 AI would be a dandy, and I'd take one of those in a heartbeat, again on the right SA. Those are 4 great fun cartridges listed especially if you're a 7mm nut.

Did you really think you wouldn't be chalenged after making an imflametary statement like that. The 7x57 can be made to shoot as acurately as any .284.

Von Gruff.

I still think that the 7.x57 Ackley is the best all around 7mm out there.
Exellent velocity, great accuracy, easy to form the brass, and its very efficient.

I can get pretty good velocities from a 99 Savage in 284, almost on par with a 280 or 270 but not quite and that is mostly because of the spring in a 99 action..cut about 2 grs. off of a .280 or 270 and they about duplicate a .284.

The 7x57 AI is an awesome round and Ackley himself said that that in all his years of work improving a multitude of cartrides the 7x57, 257 Roberts, and the 250-3000 Savage were the top three and showed 300 plus FPS improvement. That is sugnificant for sure..

All that said I have a 7x57 and 257 Robts and both are standard except I have 30-06 magazines and long throats so that I can set my bullet way out yonder and I get 7x57 and 257 Roberts IMP velocities..Just another way to skin a cat..

I think the .284 has a place in the scheme of things, and that is in the Savage and Win Lever and auto actions..If I want a bolt gun of the .284 class then it will be a .280 Rem. or a 270 Win. I see no purpose to an action that is 1/4 inch shorter, it has nothing to offer IMO..at least for those that can chew gum and walk at the same time..:)

My results with the .284 in a 99 are just about like Ray's. It comes up about 100 fps short of a .270 or .280 with the same bullets weights just because the 99 starts to get a little sticky sooner than a bolt action. In the real world that doesn't mean much, as it will still kill the same animals if you point it right.

As I pointed out on another thread, the .284 was designed to get approximate .270 ballistics in a lever or semi-auto. If you want a bolt action instead there's really no reason not to just do a .270--or .280 or 7x57. In a 98 Mauser action and the same barrel length all three of those rounds will pretty well do the same things, unless you want to get nit-picky about chronograph numbers. In the field it's pretty hard to tell the difference!

.....hurrah!

I understand the infatuation with a 7x57 AI,and how much fun it is to dream this stuff up...... I hear this stuff all the time...but will someone explain to me what the hell this offers,in the same length action, that you cannot get with a 280.....and with factory brass!.....to boot!......imagine that!

There is nothing to match the delusionary visions of wildcatters!Too funny!

I suspect the excitement has to do with that magic advertising word "improved" It's like "extra added bonus" but not as redundant.

As if anybody could improve on a cartridge that has now been killing all sorts of big game for 117 years now.

JB: Forgive me if' I'm mistaken, but wasn't a lot of this AI stuff done when there were not so many cartridges around to fill all these"imaginary" velocity gaps? And to make those existing cartridges,like the 7x57,do things that are now accomplished with standard factory ammo in standard cartridges?

The term "7x57 Improved",to me,seems like an oxymoron.....like 375 (Improved?) or 30/06 (Improved? aka 300 WSM)or, (possibly the most utterly useless of all,as it sits squarely in the tiny ballistic world between the 280 and 7 Mag (the 280..Improved???)....

A 150 7mm bullet at 3050?...one trip to Walmart for a box of Remington CoreLokts, 7RM...you got it!

Don't hurt nothing, can still fire factory ammo, don't need to mess with case trimming and leads to more trigger time (generally speaking)

Guess those are downsides for anti-blue tape types.

Doesn't hurt a thing, Scott.Just kinda funny sometimes when it's taken seriously.
