How much do you want to spend?

For around $1,500, you could buy a Howa 1500 donor from Whittaker's for around $350, a barrel from Shaw for $???, and a McM Edge fill Compact or Model Seven stock for $600ish.

Or, you could buy a Montana and have it rebarreled for about the same price.

Or you could buy a used Montana or 700 MR in 257 Roberts.
