it'll work with any barrel or a short action, they are set up for making the most out of the high BC bullets, they don't really get to do they're job till beyond 600 yards.
Unless you wanna shoot ranges over 600 yards, I'd say 25/06 0r a 270. ya want a 6.5 with better barrel life go with a 6.5/06.

My wife has a 6.5-284 Shilen (drop in) for her Savage 12 Varminter. Fantastic cartridge, very easy to tune for. HEAVY hitter on coyotes to 700yrds (farthest she's had so far), and great performance on deer. Like Ridge mentioned, if you're only wanting a 400yrd rifle, then the 6.5-284 is probably not going to benefit you much. The 12 is a short action. For really long seats, it's a single loading proposition, but it wasn't a problem getting things tuned to a COL that will run in her repeater.
There's actually been a shift for long range shooters back to the .284 Winchester, and the improved .284 Shehane (approx 100fps improved). The 6.5-284 is a barrel burner. A little nicer on barrels than a 7mm WSM, but not much. Hitting the magic 2950 with a 180grn Berger (published BC = 0.684)from the 284win might exceed your reloading manual, but there are plenty of guys doing it over the bench (Reloader 17). My next barrel will be a .284win Shilen...

The 284 is just a bit better on barrels than its 6.5 offspring due to the short neck and long throats associated with that case set up for long range shooting. the bullet has left the case neck before pressure hits its peak, exposing the throat to the max pressure flame. this is the way it was explained to me, I know guys with 6.5 gibbs that have gotten 2500 rounds from the barrel, running a 140 125 fps faster than a 264 win mag. thats unheard of n the 6.5/284 and 2900 is about as fast as they'll go.

I have a Remington XP100R pistol that is chambered in the 260 Rem cartridge. I bought from my dad awhile back and have used it to kill deer very effectively out to 250 yards with a 120gr. bullet, when my dad owned it he killed a couple of elk using the 140gr. bullets. It is a very accurate gun and a very good hunting round. I have been concidering getting one in a rifle, dont need it but would like to have it.
