I am in the market for a slb 2000 in .308 with an additional 6.5 x 55 barrel.I live in the wonderful blue state of california .I have seen a couple of these in 30-06 on auction sites , but no .308 .I would ideally like to start with the .308 or 6.5 x 55 .So if I started with the 30-06 where could I purchase additional barrels ? And or the .308 or even the .308 target model. How much do the barrels run $ ?? Please forgive me if I am asking in the wrong place and please point me un the right direction . Thank You !!!!!!!
