I've red several guides and i'm searching for this information. Is there a Mastery Cap ?
I think that for MM it's self-explanatory : Mastery just grants on ranged attack a chance to fire an additional shot. So we can't have more than 100% chance to fire an additional shot.
But for SV, the mastery grants an increase of elemental damage. So it will be possible that mastery inscrease elemental damage more than a 100%. It's the same for BM.
So what do you think about it ?
