I took a pair of pliers and squeezed a Crosman pointed lead pellet, then I took a Gamo PBA and squeezed it too, with the same amount of strength.
Both pellets (.117 cal.) flatten down to 2 cm.
Judging by this test, I can say that there is no real difference in the hardness of the two metals/alloys.
So, there is no way these Gamo PBA pellets can wear down the rifling in a air gun's barrel faster than lead pellets.
What's more, I think due to the gold plating these PBA pellets have, these pellets should cause less wear than regular pellets and should give some protection (some gold plating on the rifling of a air gun) that should protect the barrel agaisnt lead fouling/rust in the barrel.
Try the plier test for your self.
Sincerely,
Eddie
