Difference between .338 Lapua Mag, .338 Win Mag and .338 Norma Mag

#1 Post by Tallguy »

Could someone please explain the difference between these 3 calibres? If I buy a .338 Lapua Magnum rifle can I load it with either Win Mag .338 or Norma Mag .338 and vice versa?

Thanks in advance.

Not interchangeable as they have different case geometry so they can't be swapped between each other.
