You can only do it if you have skill with the gun though? It's totally not unlimited ammo. It's just the only gun that really rewarded you for landing crits.. It's not a crutch, it's just a very good situational gun... Plus all the bosses are just massive bullet sponges so what the -blam!- are you even talking about? All you do to every single boss is dump 100+ shots into him.. Why does it matter to you what I use?
