I have a 1A 7x57, 1S's in 9.3x74, 30-06 (24") and 300 H&H, and 1H's in in 375 H&H and 450/400 NE. I like the handling of the 24" barrel length best and if I had to choose one to keep, it'd be the 1S 30-06.

I did handle a 24" light barreled 1S in 250 Savage (I think) a couple years ago and really liked it. That configuration would probably be my 1st choice, though would prefer a different chambering.
