No. I have Morytania hard done and with max loot chances and sometimes I get just bolts and coins. Honestly barrows isn't worth doing unless you have maxed gear. If you get like 85 magic and arceuss spellbook, you can make a lot of money per hour by using rings of dueling and barrows teleports to restore prayer.
However, I still make around 350-400k profit per inventory using maxed pray bonus gear and toxic trident @ 76 magic. And I get about 2 inventories per hour so i'd say 700-800k profit per hour without a barrows piece.
