I believe the Swedish Mauser is very strong. Even the first ones from Mauser were made with swedish steel. Swedish steel has a natural high copper element and is resistant to corrosion and very strong.

I have seen M-96 Actions barreled in .270 winchester. It was a Swedish company that done this. The barrel was marked Cheetah and proof marked. Even Norma makes a very high pressure load for gunsmith inspected M-96 rifles.
If the M-98 never came around i think we would see the Swedish Mauser in a differant light.
