There is an article by Lane Simpson in the October 2008 Shooting Times about Nosler making the brass and loaded ammo.  Nosler is also offering 500 of their rifles chambered in .280 AI.

Pretty cool deal.

3000 fps + with a 160 gr Accubond.  The Nosler brass makes it easy even though fireforming the regular 280 rem brass can be quite accurate as long as you don't go through the process of forming a false shoulder
 
This was with a slow lot of powder so anyone looking, don't duplicate without working up in your rifle
 
62 grains of RL25 has been a more consistant performer for me lately though.  If you get a tight neck then you will have to deal with do-nuts to maintain accuracy
 
Love my 280AI!

If I were limited to only one rifle for deer hunting, I'd reach for my 280 Ackley with no regrets. Mild recoil, accurate, easy on barrels, flat shooting, great brass life and more than enough power for Deer and Elk.

Realisticly, it's probably around 75-100 fps.

I liked the 500 fps difference!  Excellent  Can I quote you on that Roy?
 
IMO (admittedly severely biased) the 280AI is a caliber that can go on any hunt you have in the lower 48.  The 270 is a little small for Elk and the 30-06 is too slow, at least with heavy enough bullets to have decent sectional density.  The 7 mag is OK but sometimes it is too fast and the bullets get squirrelly on impact.  The 300 win mag is great but kicks harder than it has to.
 
I like bullets with good sectional density to travel right around 3000 fps.  I'll settle for 2900 fps and will throttle back at 3100 fps.  That way they might not get crazy at 50 yds and will still have enough to do good at 500 yds.
 
IOW, if I'm going Speed Goat hunting I will take my 280AI and my 6.5 rem mag.  For Elk it will be my 280AI and my 300 win mag (or maybe the new 338RUM when it gets here).  Rain, I'll take the stainless 280AI or shine take the other one.  Means I have to leave my Steyr 30-06 in the safe.  Sad  I'm getting too many guns.

Anyone who ownes a .280AI is probably a reloader or has a really good friend that is. I don't see that changing as the price point for a box of .280AI factory ammo from Nosler is around $75 dollars.

My Ackley is strictly a hand-loaded proposition. I would never pay 75 bucks for a box of ammo.

Just got the Shooting Times mag in the mail today and I wished it had more load data. Turns out that my estimation of velocity gains was pretty close to what Simpson stated as well. The other thing I forgot to mention was that the Ackley improved cartridges generally have longer brass life as well.

Seems to me if you drop the weight of the bullet down you can get the speed up quit a bit.  May be its just me but Im thinking walk closer rather than paying $70 a box of ammo or having to fire form brass.   I guess cost of ammo must be more important to me than it seems to be to some of you guys.

cost is very important to us guys which is why we reload everything we own i can load an assload of shells for $70 and with the .280 ai your getting near 7mm mag performance from a non belted case

Walking closer is always an option. Now, for the guy who has the standard chambering, going to the "improved version" yields very little from a practical standpoint. I had my 280 Ackley build from the start as such and I don't have any regrets. Yes, fire forming is a pain in the arse, but once you do this, you are good to go. Ackley improved chamberings get longer brass life than there standard cousins, so that is a benefit as well. With the cost of factory ammo being what it is today, reloading just makes sense. If you do not reload, there is no reason to go Ackley improved. In the end, it is the sum of the improvements that makes the whole.
