In most countries and I am sure Europe is the same
it is hard to get transport companies to ship Ammo

It is also very expensive unless it is done in bulk due to
the dangerous goods charges involved.

Call one of the gun shops in Norway and ask who delivers the
Winchester, Norma ammo to them and then call the freight
company.

Northman - just out of interest,
what ammo are you after that can't be purchased
off the shelf or reloaded from components ?

500 Nitro
