Pick one!!

.284 Win if you are stuck on a 7mm.

Brass should last almost forever if it is not taxed, no belted cases to deal with, standard bolt face, barrel life should be upwards of 2000 rounds or so for max accuracy life but would go longer if you don't mind the odd shot going somewhere other than where you wanted it to go.

little off topic but for my own learning, why are belted cases more off a pain to deal with?

They are and they aren't. They headspace off the belt and not the shoulder. When you chamber them, you really have two dimensions instead of one that you have to work control. However once fired, many size to bump the shoulder 0.001-0.002", which takes the belt out of the picture, and gives better case life. Recently I have tried using the FL sizer to only size 2/3 of the neck of a belted mag, which probably leaves the shoulder a touch tighter than that. So far it is working, but at some point I will likely have to bump the shoulder again.
 
I like the 7mm Rem Mag. I am only neck sizing, and so far am getting good case life. Brass is cheap, good selection of bullets, plenty of down range power for most hunting situations.
 
I'd have to go with 7saum, long neck works well with any bullet and you can get decent velocity without hotrodding it to much. You can also build on a short action if want to.
 
I run a 284 win in a long action. Its an incredible caliber. As mentioned above, brass is great, I've necked up 6.5-284 lapua and run straight old winchester brass. The win took a pile more prep but runs just fine (worst with the win brass was culling it for weight and crap primer pockets, but is cheap).

With some of the newer powders out there (most note worthy RL17) velocity with the 7mm heavies is very good (h4831sc also produced good results with slightly lower velocities). I've had great results with the 168 and 180gr berger hunting vlds.
There are a ton of good hunting bullets, barns, nosler, etc that produce some nice 7mm choices.

And, in the 160 to 180gr range, its easily got enough juice to off most large Canadian game.

Recoil is very manageable.

Take care

Does the .284 feed well from a LA? I have a blueprinted LA, standard bolt face already , might be the ticket. And the Lapua brass is a huge plus!!!++++
 
7mm rem mag, it gets any job done and there cheep to load or buy ammo, huge bullet selection form around 120gr to 190gr , clearly any .284 can use the same bullets but not all of them can spread over the whole range.

personally i own a huge selection , and every time i reach for a gun its my trusty rem 700 7mm rem mag. 24 inch , cdl put in a thumbhole stock trigger done to 3lbs , 168gr burger , 68grs of retumbo, 2800fps. shoots a tight clover leaf at 100yards and sub out to five , witch im sure may be my fault(im not a sniper)

killed , moose , bear , whitetail ,muley, coyotes , gofers, grouse , and a partridge in a pair tree....but no ram yet crappy gun wont let me get on a big sheep.

that being said ive seen a gun that didnt kill what you shoot it at , as long as you do your part. but i will stand up for the 7mm any way.
 
I love my Sendero in 7mm Rem Mag, however, I wouldn't necessarily go that route again.

If I was building a rifle on a short action, I'd strongly consider a 7mm/08. You'll get far better barrel life over a magnum cartridge and if you get bored with it at some point, you've got a ton of other caliber choices that you can re-barrel to.

If I was building a long action, I'd go for a .284 Winchester AI. The same relative velocities of a 7mm Rem Mag. using 10gr. less powder in the process. The .284 Win. will be less over-bore than 7mm Rem Mag. which will definitely improve barrel life. As an added benefit, the standard bolt face offers a greater flexibility in cartridge choice if you want to re-barrel in the future.
 
7/08

I already hunt with a 7-08 AI, it is a super lightweight, and a great cartridge and rifle. I am looking to build a gun that is more hunting/target shooting capable than the 6lb'er. I like the .284 and the 280/280AI for sure just not sure which? Here is the 7/08AI that Rembo built.;) I also have a 15-16 lb target rifle, I am trying to fill the gap between 6 lb rifle and 16lb rifle.

Feeds best from LA. With the bullet selection available now, and new powders, you would be way better off running the long action. Any of the 160+ grain bullets would be seated very far into the case with a short action (loading in an internal or external mag). Go LA all the way. With my internal mag box, long action, the 180 bergers are still sticking way out there. A short action would never work as nice.

Feeds like butter.

The lapua brass is a big plus.

I've been a long time 308 shooter, had a 300wm for a while, but playing with the high BC 7mm bullets is a blast, after years on a 308, its like cheating (well i guess it is) when huckin long range with wind.

Forgot to add,,, WAY less recoil than 7mm RM or 300wm. The 284 is not a 7mm RM, or 7STW, but loaded well its very close ballistically and much nicer to shoot.
 
I built my .284 Shehane on a single shot short action. If I need to pull a loaded round the bolt must be pulled, but empties are no problem to extract with the SA.
