No, they don't laod to maximum pressures - the European ammo (and you did not say which brand) loads to the original velocity and pressure specs.
The VihtaVuori Oy manual lists, for example, a 6.5 Swede 140 gn slug at 2626'/sec with 46.4k cup pressure.
Sellier and Bellot (Austrian, I believe) is most excellent factory European ammunition at original specs and shoots incredibly well in my rifles. The PRVI ammo is next down the line. Norma, if ever available, is excellent quality ammo.
If you have loading dies, access to VihtaVuori Oy powders (try Midsouth, one of our sponsors) and bullets, you can make your own original European loadings. The VV loadings for the 303 Brit, 8mm Mauser and 444 I have used are incredibly accurate. HTH. Mikey.
