280 Rem. Or 284 Win

i would go 284 as i like short actions. not really much difference between them. not may rifles chambered in 284 but there is huge selection in 280. if i was doing a build my first choice would be the 284, every one and his dog has a 280. second choice would be 280ai.
 
IN a new rifle, what is chambered in 284 Win these days?

It's a semi cool case, a bit too long for a real short action when using long bullets, nowhere near long enough to need a long action.

I would say not true. I wouldn't build one in a Model 7, but mine works just fine in a Model 70, and I know it works great in a Model 700 too. I have my OAL at 2.930" with 140gr TTSX's and have no problem getting the 54.5grs of H4350 needed to reach 3000fps. The case capacity of the .284 is less than a grain of water different between it and the .270 WCF. I have loaded 150gr Ballistic Tips behind 58grs of H4831 for 2900fps, and 160gr Sierra BT's with H414 for 2800fps. All worked great at 2.9-2.93".
I love mine, and wouldn't think twice about building or buying (where do you get a factory one now?) another one over a 280.

Here is some eye candy if you like the .284:

280 is the painless way to go.

Rem338Win has a beautiful 284 Win, but short action M70's are hard to find and the list of guys who can build a 284 on one that runs right are short. And the guy who built this one? Chances are good he's not interested in doing it again... ;)

For the extra 3 oz or so and 1/2 inch you put up with in a long action over a short, I'd now go long action every time. Speaking of those two cartridges specifically.

x2 to what Rick said. I love the 284 (being yet another owner of that one pictured) but it takes the right builder to build one that feeds right. Everything has to be perfect (and that one is).

I like the 280 or go the route I went and go 7-08AI. Now THAT is an easy rig to deal with and still lands a guy close with velocities that are quite acceptable.

The 280 sure is an easy working rig though, so I'd have to give it the nod. The 284 gets the COOL factor every day of the week though...
 
I've always though a .280 Rem would be an excellent bolt action rifle - if you reload. I hunt with a .270 now and find it perfect for everything I do. The .280 should be essentially the same but have a much wider selection of bullets available.
 
In a hunting rifle, my choice would be the .280. The .284 is at its best when chambered in a long action, so if you are going to have a long action rifle anyway, the longer cartridge would be my preference, and going with the AI version would provide you with a little more velocity. The .280 AI is the one Ackley cartridge that has tempted me. If you are determined to have a short action rifle and choose the .284, you may find that you have 7-08 velocities due to the short OAL for the cartridge to work in the magazine. Not that there is anything wrong with 7-08 ballistics, but that is not why you chose the .284. So if you choose a long action, choose the .280 and if you prefer a short action, stick with the 7-08.
 
When the case supplys start to dry up, as I think they might with all the import sh*t going on these days, a 280 case will be much easier to get hold of or make than a 284.
 
I believe that Lapua makes 6.5-284 brass, so there will be a supply that doesn't have to come north there. Back when you couldn't buy LW rifles, I built my 284 mountain gun on a Rem 600 action. Modified the mag box and follower to allow 3.1" col (and to feed properly), and fit the whole thing into first the original stock and later a LW synthetic. Topped it with a 2-7 Leupold compact. Synthetic sling, and presto, a 6 pound all up mountain rifle. I wanted a LW gun that would push a 140 gr bullet at 3000 fps, and that's very close to what I ended up with. I have also had 280 and 280 AI rifles, and am working on a 7mm-08 AI right now. In terms of terminal ballistics, really, not enough difference to worry about. But if we didn't argue the minutiae, what would we talk about here? - dan
 
ein still makes 284 brass and its avalable. i recently bought a couple of hundred. i have a 284 built on a sako action, feeds great and is very acurate.
 
I have two 284 winchesters, one in a browning micro medallion the other in a browning hunter, I love both guns but, I find with the newer longer bullets , hornady interbonds, nosler accubonds ect, I have to be seat the bullets past the bullet ogive to fit the magazine so bullet selection is limited in my guns. In a long action you could seat the bullets out longer but that defeats the purpose of a light weight gun. Go with a 280 rem and dont look back.
 
Some short actions allow longer col which solves that issue. You can also modify some short actions to accommodate longer col's as I did. If you like the cartridge or are working with a SA, there is no reason to trade your gun in for a LA version. And ballistically speaking, the 280 and 284 are almost twins. - dan
 
.284

The two best powders I have found for this cartridge are H414 and H4350. The max loads with both of them that come out to 3000ish with a 140gr and 2900ish with a 150gr leave plenty of room for a 2.800" OAL. Ramshot Hunter is supposed to work awesome too, and is a very dense ball powder, and should aso give you lots of room. If you don't need to use a 160 VLD there is room to play.
I would like to try RL17, and see if it will improve velocity, but it is hard to argue with a 140gr TTSX at 3050fps shooting 0.25-.50" consistently.

I also remember being able to fit my hunting loads into Rackmastr's 7-08 AI, so a Model 700 should work fine for a sweet .284.
