I'm not sure who determines emc values for things in modpacks, but I'll leave this here just in case you can do something about it. Antibarrels' emc doesn't change when you put stuff in it, but when you transmute antibarrels with Project E, if they have anything in them, the transmuted antibarrels also have those items. It doesn't work with regular barrels.
