I like long barrels, and the .280 NEF tends to be a good shooter. 7-08 uses a little less powder and kicks a bit less, and the 22" barrel is a bit more compact. 7x57 and 7x64 were available in 24" up until 5-6 years ago, might find one on the used market. Really isn't much you can't do with a .308 that you can do with a 280 or 7-08. You could go for something a bit more different, like a .223, .22-250, .243, or 25-06.
