Agree. As you download you reduce pressure and that reduces the burning regularity of the powder and can be detrimental to accuracy if you don't handle it in a systematic way that probably requires more ammo than you have.

The Swedish action is not a strength wimp. I know a gunsmith who chambered one in .350 Rem Mag. As Jimro said, the issue is the lack of safety features, so the main thing to concern yourself with is good quality brass in good condition that won't fail prematurely. Norma has that covered with new ammo, so you should be just fine. You can then go on to find a milder load for yourself later.

Understand that as long as the gun isn't severely corroded, it will withstand proof loads that are 30% warmer than factory ammo. A steady diet of them would eventually set bolt lugs back more than is best for strength, but small numbers of slightly warmer than usual rounds should not be a dietary problem for it.
