Cant find any 280 ackley ammo, i dont reload so was thinking of grabbing 280 rem and sight it in for hunting. Anyone know if the accuracy will be shaky with the 280 rem?

Accuracy should be OK. Only one way to find out though.
I prefer classic. Semper Fi I used to run with the hare. Now I'm envious of the tortoise and I do my own stunts but rarely intentionally

Depends on the ammo and your rifle, but in my rifles chambered for various improved cartridges (including one .280 AI) accuracy of factory ammo has always been good enough to kill deer out to 300-400 yards.

NICE selection of bullets available in custom "factory loads" at the above link. The one I'd recommend is the 145 LRX. But, at that price, you will probably want to get started loading really quick.

Cant find any 280 ackley ammo, i dont reload so was thinking of grabbing 280 rem and sight it in for hunting. Anyone know if the accuracy will be shaky with the 280 rem? I have a custom .280 Imp. (RCBS version), that I have been shooting .280 Rem. ammo in exclusively. Last week, I chronoed an old supply of Federal .280 Vital-Shok ammo, with the Nosler Accubond 140 gr., that went 3112 fps. I shot two, three-shot 100 yd. groups measuring .85" out of my Ruger #1, which makes me very happy, accuracy-wise. About the best I have been able to do with this rifle, and fire-formed handloads with this bullet, is 3175 fps. For me, the answer is pretty easy- shoot the factory .280 stuff!

You are going to have to reload, and even at that, nosler .280 AI brass is no where to be seen either. But fireform away.

I have not confirmed in my 280AI, but generally what I've seen quoted on here is about 100fps loss when using standard in an AI rifle.

you should have no trouble selling the brass after you form it in your rifle

Very easy to make 280AI brass from 30-06 brass. Shooting 280 ammo works too.

I never chrono'd factory loads in my AI, but have fired a couple boxes of it. Accuracy was good.

Chrono'd three Nosler factory loads at the range. Was only 34 degrees with a PA of about 60 feet. Have read velocity slows between 2.5 - 4 fps per 1.8 degrees so that factors in.
...............Claimed.....Actual avg.....spread..... diff 140 ABs........3150........2983............49.........-167 150 LRABs....2930........2904............10.........-26 160 NPs........2950........2736............31.........-214
I would expect a difference with the cold temps, but a 214fps difference? Claimed looks real for the LRABs

My Kimber 280ai shoots Remington 150 grain corelockt 280 ammo under an inch at 100 yards. I chronoed them at 2800 with a magnetospeed.

I have never loaded a cartridge that lost 160-214 fps going from 75-85 degrees to 34F. Thats also pretty pathetic for factory ammo for a case thats supposed to be so "cutting edge".
The 280 Remington is overbore.
The 7 Rem Mag is over bore.
