Afro- if its NOT blasphemy,
A 338 barrel, on a 333 chamber, which means 333 cases loaded with 'modern' 338 bullets? Will the 333case take the bullet difference??
Otherwise , are we running 338 per 333 specs?
Intriguing, economical and probably do able-until we get a large run of metford barrels in 333 ?

As Huvius stated at the beginning, we can stamp 338 under the bbl? Will Tophet's suggestion of a colombian action do? I'd like to save the argie 09 for the metford barrel...
