Sorry if this was mentioned before, but what are the best bullets for defeating expert plantera using megashark? I am debating between crystal and chlorophyte, but maybe there are other better bullets? I am pre plantera so no I can not have venom bullets.
Both are good
If you can't aim well and want pure damage, choose chlorophyte
If you're going for DPS and want something cheap, choose crystal
Considering you're using a megashark, crystal might be the best bet. I used party bullets to defeat it the first time, though, mostly because I'm a tightwad and those bullets are the cheapest available.
