I think if you were looking for a longer reach, beyond 200m, I'd go cheaper. I'd personally zero in on the Moisin-Nagant, it's sturdy, accurate, and the ammo's cheap as hell. It's a bolt gun, but the distance rapidly narrows the fire rate advantage of a semi-auto.
That said, looking at the caliber options the OP asked about, it seems he's zeroed in on an intermediate round anyway.
