I have a Custom Made 308 norma. Build was done by Guy smith out of Akron Ohio, aka Smitty's Gunshop. It has the Eddy stone action, and a 24" non ported barrel. Weighs a ton. After reading about the new 338, I am considering rechambering to the newer round. Can it be done on my current frame, or are we talking the extreme makeover here ? Cost of ammo brass is a not a worry as I have reloading for my norma and everything else I own for about 20 yrs. I am thinking of this conversion due to current situation that Bars me from dropping 3k on the table for a new build. I am building a house , dam its expensive !! Any pros and cons greatly appreciated.
