I'm partial to 24" barrels too. One can have a 24" .280 without breaking the bank. A couple of years ago Midway had a great sale on some of their Adams & Benett barrels for Savage rifles, so as an experiment, I bought one in .35 Whelen along with the tools to make the swap. The rifle is an old beater 110 with that bendy synthetic Savage stock. It took all of an hour to swap the barrel the first time...it was easy to do. Best of all, the Whelen shoots great. 1"-1 1/2" all day long with inexpensive bulk cup and core bullets--even the short 200gr Hornady RN.
That was fun, so I checked out Midway again, and sure enough there was a 24" .280 Rem barrel on sale. I think it was $90. This time the barrel swap took 40 minutes and it groups better than the .35 Whelen--right around an inch, if I do my part. I never chrono'd the .280 loads, but we played around with it at our 300yd range and it was as flat and accurate as the .270WCF we compared it to.
The .280 Rem was replaced by another caliber I've wanted to see in a 24" barrel--the .257 Roberts. Talk about sweet! Groups 1' or less are the norm @ 100yds. Very low recoil, which is becoming more important to me the older I get. I think this is the barrel that's going to stay on the rifle for this hunting season. The .280 has just too much ooomph for the small whitetails here in Georgia.
Anyway, if you really want a 24" .280 Rem it's doable without breaking the bank. If plain old Savages aren't fancy enough, one could buy the "pretty" Savage Classic they have out now and swap with an A&B barrel. All I can say is that old "beater" 110 looks pretty good to me right now. Be careful, though...once you find out how easy it is to do these swaps, and how good the A&B barrels are, you'll be sunk--it's truly a sickness.

I have 5 of those barrels now, plus all the 22" take-off factory barrels. If only they'd make a 6.5x55. With all the other calibers A&B offers, you'd think that one would be a no-brainer. Oh well.
