I didn't think so.
I know factory loads can be on the light side but the Magtech factory loads I shoot say its 260Gr at 1,800fps with 1871 Ft.Lb's of energy at the muzzle.
I wonder why they say,, "the .460Roland has 27,000 foot-pounds of muzzle energy" on there site? Thats crazy!!
Scroll down to the 7th paragraph on there site and read it for your self,,,(For Maximum Fire Power) http://460rowland.com/about/
Something don't seem right here,,,,
