While it is not practical to use platinum coins to fund the coin gun, its actual practical use with silver coins makes it a good single target DPS option. Not to mention it shoots 5x faster than the sniper rifle making the coin gun one of the highest damage output capable weapons in the game. Using platinum coins is not a cost effective option, but the damage from platinum coins rivals even the sniper rifle which has the highest base damage in the game. Despite its expensive use, it boasts one of the highest damage outputs in Terraria. It uses coins and the higher grade of coin you use will increase its damage. The coin gun is interesting as it does not utilize regular bullets. There are 36 different types of guns and this list will narrow down the best guns you can find throughout different stages of the game. You will have to fund your gun-slinging through the arms dealer or finding bullets throughout your world. The downside to using guns is the fact that you cannot craft bullets. Guns have the advantage of using bullets which have a higher velocity than bows and arrows. You will mostly find yourself using bows or guns if you decide to play a ranged-based playstyle. High Fire Rate with even Higher damage and the fact that it explodes into sharpnel makes it even more deadly.The ranger class in Terraria has two different types of weapons to choose from. One of the Best weapons in the game, it can kill almost anything in a matter of seconds. It is amazing for carpeting arenas with Mines in preperation for the Pumpkin Moon, Destroyer, Plantera, or Golem. Close Range combat with this weapon is suicidal, and not advised. Known to deal over ~500 in a critical hit, it can be absurdly deadly in long ranges due to it's fast speeds.
Chlorophyte Bullets is also a good alternative. Combined with Crystal Bullets, and you can deal over 1000 Damage in a single shot due to Crystal Shard Spread (not even taking into account about Criticals). Extremely Slow Fire Rate but Absurdly High Base Damage makes this a notorious weapon in PvP. With the Best Ranger Gear, it can kill Pumpking in absolute seconds. Auto-Fire and Obscene Base Damage makes this a even greater contender when combined with Crystal Bullets, as the ~18 Crystal Shards produced by the intitial impact will make it extremely hard to escape in PvP. Best weapon in terms of DPS, with piercing, over 50 damage PER STAR, and absurdly high fire rates, in exchange for being one of the weapons that have the most trouble acquiring ammunition for. Gel is slightly hard to come by in Hardmode, so farming Slime Statues for Gel is recommended. High Fire Rate and Pyrotechnic Demolishment in PvP makes this weapon a great contender, even against Coin Gun with Hacked Platinum Coins.
Chlorophyte Bullets ARE recommended, but in fights where there are multiple enemies that do not contribute to killing the actual boss itself (Destroyer's Probes, Skeletron Prime's Arms, Plantera's Tentacles, Scarecrows/Hellhounds/Poltergeist/Splinterlings in Pumpkin Moon, etc), it can be detrimental and a waste of chlorophyte. Absurdly high fire rate combined with high base damage PER BULLET makes this a popular choice amongst the Terraria Community. Very similar to Stake Launcher, albeit with the ability to poison. Piercing and Passively High Damage in exchange for absurd rarity and no use of special ammunition makes this weapon a rewarding weapon for the precise and accurate. This thing will wreck anyone you come across in PvP, and wear down boss health like no tommarow. There is a lot of competition between which is the best "RANGED" weapon in Terraria.
