Hi, Thinking of building a .338 Snipetac and I beleive the barrel most use is a 32 inch Idaho or Light Idaho profile. I believe I need a 1.450 shank ..what is the taper to the muzzle. Muzzle diametre? Because of export /import permit restraints I most likely will be using a lilja barrel but I need one to close to the Idaho spec I beleive. I have a 1.350 Taper 31 at 30 inch in the sytem for a Lap improved but my buddy is keen on going a 338 Snipetac on a stiller 408 action. Any help with the Idaho barrel profile would be appreciated.
