Of the ones I have, I like the 22-250 AI as much as any. I know I shoot it most. I used to shoot the 7mm TCU a lot for pistol silhouette. The 7mm International was popular back then. I see the 257 AI for sale sometimes and the price is a bit below the 257. I'd think the 6.5-06 Ai would be up there and it hasn't been mentioned.

I prefer classic.
