Don't go shooting any of the overpressure loads out of it without direct confirmation from Ruger that it's safe to do so.
I know a lot of the overpressure loads are marked "Ruger Only" on the box, but that's honestly a terribly inaccurate statement because not all Rugers are designed to handle overpressure loads.
That being said, there's no valid reason to go shooting overpressure ammo anyway unless you plan on hunting Polar Bears with it, as such ammo is extremely expensive and isn't exactly what most folks would call "fun" to shoot.
