They're very durable but built on the small ring Mauser action and not the large ring 98.
Is this a bad thing?
Its fine for what it is. You're limited in what you can build on it.
I had a 4000 Lightweight. $600 and under is a good price.
Husqvarna built 270 Win, 7mm Rem Mag, and 358 Norma Magnum on the same action. Ask me how I know.
All of these are loaded to very high pressure in factory ammunition.
I also have them in 9.3X62, 30-06, and 7X57.
The Husqvarna 1640 small ring action is as strong as the large ring '98. The left locking lug is actually stronger than a 98 lug, as it is not split for the ejector. The ejector is positioned beneath the lug raceway, consequently that left lug is solid.
The 1600 series action is not to be confused with the small ring 94 and 96 Mauser actions.
