Looks like no better then a 7-08 by the quick load Data and in REAL life there isnt much difference with GREAT handloads ! RJ
6.5 x 284 is only around 2950 fps - RJ
the 284 is about 20% larger capacity than the 7-08, which means around 5% more velocity, apples to apples (135 fps +/-). If the 284 is loaded to a longer non SAAMI OAL it will increase a bit more yet
Running QL data to the same specs as the 20" 284 above, the average velocity for the top six fastest powders is 2783 fps *for the 7mm-08 Rem 20"

I run a .284 in a factory 22.4" Tikka Superlite barrel(rechamsbered 7mm-08) and a T3X compact(20" barrel) in 7mm-08. If you were looking to rebarrel the 284 with something like an 8 twist I think you would see a pretty reasonable advantage running bullets heavier than 160gr, but with the factory 9 1/2 twist I stick to shooting 145gr LRX's in the 284. Granted I don't have the throat cut quite as deep as I probably could to make the most of the action length, but the velocities I'm getting(as TB suggested) are about 100-150fps gain over the 7mm-08 with the same projectile. And that is with the roughly 2.5" longer barrel.
Damn you Dave, you know I don't like public speaking.

I was getting 2800 fps with 140 gr bullets using H4831. Thats out of my Browning 20" barrel. I've always figured to get the max out of the 284 case a 24" barrel was needed. With the right powder you should get 3100 fps from a 24" barrel. RL17 should work well.
yeah......but I didn't want to type something out and then edit all of my mistakes out of it......
7mm-08, 284 win, 7x57 and 280 rem are all so close to each other, choose any and concentrate on bullet placement, the biggest factor to velocity gains between all 4 of them is........barrel length and free bore, and when you cut your chamber to take advantage of the 284 case with the bullet in the neck and out of the powder column, you need a long action, and the 284,7x57 and 280 all in long action, run neck in neck.....

I shot a few Winchester 88's in 284 yrs back but never owned and/or reloaded for a rifle in that chambering. I did have a Winchester M70 with a Douglas barrel in
35-284 that shot well for me using a variety of loads using bullets ranging from 110 gr HP pistol projectiles up to 250 gr hardcast. For me, the 284 Win doesn't do
as well as the 7x57, but the 284 case is a nice one for larger bore rifle builds such as 35 & 375 on up to 45. The 450 BM is based on a shortened 284 case.

Yes..... but you don't see 7x57 and 280's in F-class so for that the 284 has an edge. There's also a reason why Ultra Light Arms most popular chambering was 284, it fits in a short action. Those are the only advantages imo.
True, but it fits in a single shot short action, loaded to F-class specs it's 3.515 COAL, which would require a long action magazine, and, depending on what short action you're running, you have to pull the bolt out to eject a loaded round. Running a .284 in a short action repeater is holding it back from it's true potential when shooting anything heavier then 150 grain class bullets, which puts it brother to 7-08 head to head
favorite caliber of melvin as well and he is a good salesman.
180 grain hybrid in a 32 inch barrel averages 2850 FPS with 54.0 grains of H4831sc in a .284 win
180 grain hybrid in a 24 inch barrel averages 2925 FPS with 78.0 grains of RL33 in a 7mm rem mag
In a custom rig, you can make the .284 really shine, but it takes a long chamber and an even longer barrel, things not offered on off the shelf hunting rifles, and in a repeater, you won't get there on a short action platform from my experience
