The 250 AI is the one I'd really like......but then you are just .007 away from a yes, the dreaded 6.5 Creedmoor! Never was a Roberts fan, good round, but then you are almost a twin of the 6.5x55........they all get the job done no doubt. I do like the vanilla 25-06........it needs a big brother....commercialized..........
The Wins and Kimbers with blue/wood are nice.
I've done both the 250AI and 25 Souper in short action Ruger 77s and prefer the 25 Souper 'cause it is easier, one run through the resizing die, and fed better in my 77 RSI.
That said, the easiest .257" bore round is the 25-06 and although I was a 257AI snob for a long time, I have come to appreciate the 25-06, even with a 22" barrel. The Marlin XL7 that I bought from someone on this site back in 2012 shoots the Hornady American Whitetail 117 grain factory load better than a $280 rifle ought to.
