What does "These rounds were not intended for use in a polygonal style bore!!!!" mean?

I know several pistol manufactures use polygonal bores.. What kind of ammo isn't intended for them and why?

They're lead rounds.

Polygonal barrels don't like lead. You'll lead your barrel out fairly quickly running lead ammo through 'em.

So will my Sig 229 like these or not? Recommended? Not?

The Sig site mentions nothing about a polygonal bore.

I couldn't find anything on it either. I do remember reading awhile back that the GSR didn't have the same type of barrel as the other Sig models and it isn't Polygonal.
