i dont think but a used as new Savage 110 in 300 win mag cost 350$ and a barrel closely the same so that possible to get a complete rifle with a real quality barrel and with 26 inch lenght to get best velocity for less than 700 $
if you go with 264 WIN choose chamber with paralell throat and seat out bullet that far better because mag box is 300 WIN mag lenght and that seely to loose performance by the fact to have too deep seated bullet ( specialy long bullet as 140 gr ).
