You've also got the option an SVT-40. It's another milsurp from the 40's, but they are quite accurate. Some even came in a sniper variant just like the Mosin Nagants did.
An option in that caliber would be a Mosin Nagant, but one with a bent bolt in particular so the rifle could accept a regular scope mount rather than doing a scout scope set-up.
Not a bad way to spend $250 IMHO
