.284 is 7mm right??
How come nobody has mentioned the old .284 Winchester?
Well, the .284 is a short action cartridge with powder capacity similar to that of a .280 Remington. But in my opinion, the .284's weakness, as well as its strength, is that its at its best in a long action rifle so that bullets can be seated long enough, so as not to intrude into the powder capacity of the case. If the bullet is seated deeply enough to cycle through a short action magazine, the .284 can never match the ballistics of the .280 unless it's restricted to short, flat base bullets. So in short action rifles, the 7-08 is seen as the more efficient cartridge, since the .284 in a similar rifle provides little more performance, if any. For the handloader with a long action rifle, the .284 will do anything the .280 will do, and when both are loaded with very long bullets, might even out perform it. That said, the .284 falls short of a 7 magnum, so one needs to define his requirements, and simply acquiring a 7 magnum might be the wisest choice if you need more than a .280 but want to use a 7mm bullet. If you insist on shooting 180 gr VLDs, perhaps an STW or an Ultrmag is better yet.
