Home Forums Hunting & Shooting Custom Rifles & Wildcats Why or Why "NOT" a 284 Win. over a 7mm-08 in a custom short action rifle?

Rick, you could save some time and buy this 7 saum at EPPS...its a steal!

The 284 is in effect a 280 Remington, a 7mm-06, it is simply more powerful than a 7-08 under any circumstances..What you need to determine is do you want or need the added power? Both are nice cartridges. I suppose the 7-08 has less recoil, but I can't tell any differnce there, but I also shoot more and a lot bigger bores, and more so than the average shooter, so recoil is a non issue until you get to say a 458 Lott or .470.

I think that both are smoking good rounds. I am looking at building a .284 on a Winchester SA.

Lightweight Rifles Inc. Strata model on a 700 SA action with a 2.8" magazine in .284. Shoots the 140-gr TTSX with R17 @ 3100 fps at under a half inch for a trio. Tally R & B with a Leup VX III 2.5-8x

It is what it is which is very good.

Nice piece!!

I too, and you're right.



You can easily add a Wyatts box to the 700 and seat bullets out to 2.880. Plenty of length for even the longest 7mm bullets.



284 win brass is just as easy to find as 7mm08.

the 7mm WSM is king of the short action 7s

but there ain't much the 7mm-08 won't do.

It just won't do what a 284 can do.

In a short action.

Su35, last I checked 284 brass is only mfg. by WW, stamped 7/08 is mfg. by WW/RP/FC - via ammo, Norma, and Nosler, plus one can always use 308, 243, 260, etc. brass to reform and it's very plentiful. If WW brass is very plentiful in 284, I suppose one would be fixed up, but the SAUM's seems to be fading from my vantage point in terms of guns, ammo, brass, etc.

Toad, nicely said

I'm with Cliff on this one. there not much more needed for thin skinned game like deer and elk than a 7-08 loaded with the right bullets. I would not feel undergunned in the sligtest.
In my opinion too many peopel have magnumitis when its really not necessary.

65BR,

There has never been a day in the past 5 years that I could
not buy 284 Win brass. You only need one brand.
Day in, day out, it's a phone call away.



There's nothing magnum about the 284. It simply sends bullets down range at just about 280R speed.

To say the 284 has nothing over the 708, you might as well say the same thing about the 280.
What I used to do with a 280 in a long action I now do
with the 284 in a short action.

And, whatever the 7mm WSM does better than the 284, the 284 does better than a 708.




Going 284 really eliminates the need of going 708 AI.
It has a 35 degree should and another 125 to 150 fps over the AI 708.

To each his own, I know what the 284 case will do and I utilize it's more horse power in a short action .473 bolt face.

SU, Nice project there. No flies on the 284, fine round, and I agree 100%, if you can get one good brass, you are G-T-G.

You make a good point of 284 vs. AI/708 as I would imagine they would feed similarly if not more often consistently dependable in the 284 assuming the action was designed to accomadate it.

I am not 'anti-284' by any means. I just like the performance per recoil/blast proposition and abundant ammo and brass choices are a nicety.

What action are you building above and what can you tell me about feeding. I hear some actions, i.e. perhaps Sako L579 have to be opened up a little in the feed rails to smoothly feed well, but I have no experience to be honest w/284. I do believe it is a VERY efficient effective 7mm esp. in a longer bbl w/high BC bullets as is the WSM.

To me to 'AI' vs. std. 7/08 is a simple decision, as I cannot see enough performance for the hassle, but OTOH if one needs a noticeable improvement of ballistics in the field, a 284/WSM will give it w/proper loads.

Choosing how much powder one needs behind a bullet, i.e. what case to use, is in reality a function of just how far one wants/needs to shoot. PBR is close I am sure to 400 yds. As one stretches out further no doubt one can benefit more so as the range grows.

I truly believe the 284 case is best utilized in 'OEM' form, aka 7mm, or in say a 338 bore. In the 6.5, it does a great job ballistically, but it's bbl life is hampered. A 284 w/good bullets should do very well against a like 6.5/284 IMHO.

Nice photo as well of the brass and Bergers

Merry Christmas guys! ....and Gals!

Thank you,

The action is a FN SPR 70. Manners MCS-T stock.

I've never had a feeding issue with the 284 case in either win or rem. They just function perfectly.

I just completed this 6.5-284.

Rem 700 Ti with a Wyatts box I can seat bullets out to 2.880 if I want to. I load 140 VLD's no problem. As far as throat life, From my experience, if you don't go F-class with it you'll be just fine for a hunting rifle.
This 6.5 wears a 25" #1 barrel. It's the same OAL length as a 24" 270.
I get 200 fps mv over my 260.

Dang, if I didn't still have women on my mind I'd be gettin a Woodie LOL - NICE Rifle Sir!

Great stuff SU35, thanks for that, always nice when my Neurons are Stimulated! That's a Looker for sure and functional.

You look set for about 1,500 victims.....deer, etc.

BTW, whose BBL - the No. 1?

In my mind another thing worth looking at is velocity/ grain of powder. Or how much powder your using to get the same velocity. Its all about effiency

I have been considering a new .270, 7-08 or .284 and was recently speaking to a rifle builder, well known for his .284s, and he discouraged me from the .284 because of poor brass quality.

Any truth to this?

Is he perhaps not wanting to build one for another reason? Just asking. Haven't noticed brass as an issue at all.

I have had 7-08's and one 284 plus a few wilcats on the 284 case. If it was me I wouldn't mess with the 284. I wouldn't hesitate picking one up if I found a screaming deal on it, but at this point would go with something else if building it myself.
If you need more than the 7-08 in a factory round I would probably run a 7 saum. Holds just as many down as a 284 in the ones I have used and as much more performance as the 284 compared to the 7-08. The wsm has a bit more speed but the saum seems to feed a bit smoother in the guns I have used.
If you want to run the wyats mag box to extend OAL on the 284, You can do the same and run a 7x57 AI and pick up nearly the case capacity of the 284 and still fit 4 down. Mine feeds great with no rail work.

The guy who stuck the parts together for my 284 wouldn't do a 7 SAUM or a WSM. The 7SAUM was my first choice but actually now that I have the 284 and have shot it, it's enough in a 6 lb package for what I'll do with it.

The short maggies? He said he couldn't get them to feed well and had tried long enough.

What is the advantage of the 284 vs. the 7mm-08?

Around 200 fps in velocity?

If so, what value does 200 fps of additional velocity add?

Since I hardly ever shoot anything over 300 yards, except for pdogs and the occassional coyote, 200 fps would be meaningless to me, from a practical POV. For guys who, on a regular basis, shoot things at greater distances, every fps of additional velocity may be very meaningful. But not for shooting game within 300 yards.
