Not wanting to spark a Remington v.s. Savage debate I'll start by saying they're both great for different reasons.
If you want a used rifle, get a Remington 700 instead. They're the easiest to work on and trick out with after market acessories.
If you want a Savage, get a new one. I know from personal experience that it's hard to sell them used regardless of how nice they are. I like Savage's out of box accuracy but if you want to play around with accessories, go with a Remington.
With a Remington 700 in 22-250, when you burn the throat out after a few thousand rds, you can easily have the chamber reamed out to .220 Swift and have more fun.
Any way hope this makes your decision easier.
