284Win Load data
 

Hey Guys

So it looks like I'm going to be the new owner of a Kimber Mountain Accent in 284 Win.

From what I've read quickly seems to be a pretty decent caliber, Anyone have and good experience with it. I have a couple hundred 160 Grain accubonds I was thinking about loading it.

Thanks

7 MMs are pretty much all the same. 7x57, 7-08, 280 Rem. 284 are pretty much interchangeable. Anyone who claims that one is greatly superior to the other reads to much and shoots too little. The 284 is a great round, lots of good uses for it. In the conventional, non-mag 7s I prefer 140 grain loads. Barnes and Hornady both make excellent bullets in that weight range depending on whether you want cup and core or mono deep penetrating.

In the 284 Varget works great with the lighter bullets. If you shoot 160-175 grain I have had excellent results with Hybrid 100 V and IMR 4350. 100V doesn't get talked about a lot but in the 7s it produces great velocity, low SD, good groups and pressure that is about 10% lower at the same velocity. I first started using it when loading for drillings as they prefer lower pressure loads and carried it over to bolt guns because of the exceptional accuracy it delivers.

You might wanna try something lighter than 160’s, for the simple reason that if the rifle is a short action you’ll be loosing a pile of case capacity due to seating the bullet pretty deep to function through the magazine. If the rifle is a long action, fill your boots.
I’ve found 4350 either prefix to be about as stellar of powder as you can use in the .284Win, although don’t discount 4831, 760/414, and I’d guess Hybrid 100 would be a dandy as well. I also like to run magnum primers in my .284’s as well.

powder
 

Win 760/H414 are the cat's PJ's with the 140gr bullet /mag primers.

Without a doubt the 7-08 is virtually identical to the 28 nosler

Not a 284 win but all my 280’s have liked IMR 4831, some have liked 4350. I’m sure once you use that 284 you won’t be reaching for any 30cal rifles too often.

284 Winchester along with the other 7 mm rifles shine with a 140 Nosler Partition.
I shoot a lot of 150 grain Nosler Solid Base bullets out of my 7x57 .
The 140 grain Partitions clock in at 2830 fps, everything dead.

You need to try harder not to be "That Guy". Read the whole post, I was very clear I was talking about non-magnum 7s. 7 Rum, 7 rem mag, 28 Nosler, 7 STW. 7-300 are way different beasts but between themselves the comment holds, shoot more read less if you think the big mags are really that different from each other and one is clearly superior.

Tagging in as my 284 Win was just chambered last week. I am thinking of bringing in some 143 0r 155 gr Hammer Hunters from the states. I hope that R26 will work as I have a 8 pounder. I know lots of F class guys having good success with R23 and 180's. The R26 may be to slow with a 143 or 155 gr but I'll try it. The 284 is quite amazing in F class. Guys running 180-184 gr at 2900-2950 fps. But they also have 30" barrels.

I have a 284 hunting rifle in a medium length action. 3" oal or so.
In a long action go 280 Rem.
In a true short action a 7-08 Rem is the way to go.
Kinda neat cartridge. I like the lighter bullets 120-140gr.
Rework Lapua 6.5/284 brass or buy the 284 Winchester brand as there seems to be some around again.
Have fun!

28 nosler is a standard length non belted cartridge and i never said the big mags are really that different from one another at all. Never even mentioned anything close or even implied it as a 28 nosler is not a magnum. What’s your definition of a mag, belted? The standard is usually a belted Holland and Holland type case which would make the 28 nosler a non magnum thus puts your comparison to non magnum “7”s back at 7-08 similar to a 28 nosler, so clearly i did read the whole post. Maybe a bit more reading is required by some. If one merely used a comparison to the “power” of a round instead of using “belted” as the standard to consider a cartridge a “magnum” then back n the day when a 25-06 first came out then it would have been considered a magnum comparing that cartridge to what was already available in a 25, it however was never referred to as a magnum. 7-06 vs 28 nosler, both non magnums, your statement not mine

My go to load in my Ruger m77 .284 win is 56.0 gr IMR 4350 140 gr Nolser PT . Been using that combo for over 40 years shot a lot of big game deer, bear , elk + moose . It a very deadly combo .

7 RUM = Remington Ultra Magnum - not belted either, nor are any of the rest of the RUM or short RUMS. THE 375 H&H, 300 Holland, 338 Lapua don't have Mag in the name, some with belts some not but all clearly magnums. Magnum is NOT defined by a belt, though many have one, nor is it defined by whether it has Magnum in the name. I doubt anyone would class a 570 Nyder as not a magnum. There are probably more magnums without a belt than with one.

I would not, and nor would anyone I know, try to put a 7-08 in the same class as a 7 RUM or 28 Nosler, both of which are significantly over bore. Nor have I ever said or even implied they were comprable without a truly warped reading of what I have written. Not going to debate this further with you because you are intentionally trying to start an argument that has no merit and absolutely no point. It does not address the needs of the OP and is superfluous to this discussion, which is the merits of the 284 and potential loads for it.

Thanks to everyone that made an effort to comment, good or bad i'll take come information from everyone's comments and work up a load once I receive my gun. Just so happens to be coming with loads of new brass and Die so should be painless to start working up a load. I'm sure everyone is running Large magnum primers with the 284.

with ball powder
 

Mag primers are recommended.

284
 

H4350 and 140 TTSX and WMR primers seemed to work well in mine.

Thanks that's what I thought I have a couple thousand of those so should be good.

Been using CCI 200 LR primers works just fine .

I have a few hunting rifles in 284 Win. I have used Win 760 Varget and H4350 with good results. All my 284 Win are clip fed. 120 to 140 grain bullets work well for me.

Well the trade deal fell through thanks for all info once again guys.
