World of Tanks: Gold rounds and you

So we've all know that gold rounds can be purchased for tanks with credits making them widely available to the masses. However there seems to be people who don't understand gold rounds based on the complaints I see thrown out in battle and the lack of them during competitive play. The first is that using gold rounds is not cheating. You can use only gold rounds in your tanks and get all the penetrations you couldn't before so aiming becomes less of an issue, however due to the cost you'll probably be losing credits.

You can also decide to use no gold rounds at all, however when facing a heavily armored tank and not being able to penetrate it can cost you valuable experience due to the lack of damage because of missing weak spots.It is a balance since too much gold rounds will lose you credits, and not enough can see you facing up against opponents you can't hurt easily enough when you have to hurt them. However I can not go into just gold rounds without talking about the other kinds of ammunition.

AP / Standard Ammo
So the standard ammo for your tank which is usually AP though some tanks have APCR (T71) is your bread and butter ammo. (Artillery's is HE) You'll want to load most of your rounds in this ammo type, probably about 65% depending on how much ammo your tank holds. (swings from 50% to 80%) The reason why you want to have it loaded the most is that it costs the least amount of credits and is generally up for the job vs most of the tanks you'll fight against. For tanks you can't hurt easily we'll be getting into what ammo to use for those later.

HE
High explosive rounds are best used on Artillery and Derps. A Derp gun is an artillery gun on a tank like the KV-2's 152 mm M-10 which does 910 damage with 86 pen on the HE rounds. For most tanks out there HE is worthless to bring except for a small handful of rounds if you are not using an artillery gun. This is primarily for making sure you deal some damage (even if it is just track damage) to someone who is on cap. You'll probably never use them, but hey they are there in case you have troubles dealing damage to a guy capping who is angled.

Gold rounds (Anything round you can buy with gold)
For normal tanks I generally run with about 30% gold shells (APCR or HEAT). A lot of times I won't need them like in a KV-1S in a Medium tank company however when I meet up with something that is harder to pen I like to switch over to gold rounds. My best example is my IS-6 vs another IS-6, I can pen him if I try but due to angling, wiggling, and the low pen of the gun I'd prefer just to switch to gold rounds and hit him on the flattest surface. (IS-6's armor can still easily bounce another IS-6's gold rounds) Now for artillery since they are so different then normal tanks I'm going to talk about their gold rounds separately.

Artillery

• HE : Increases splash range which is very sexy and will probably be your main gold rounds in artillery. This is because you're more likely to deal higher damage through a splash hit vs your regular He rounds because of the way splash damage is calculated.
• HEAT : Great for low tier high accuracy artillery like the SU-26, it has no splash damage so you need to hit hull to deal damage (sometimes you get those annoying track only hits) however compare the damage between an SU-26's HE and HEAT rounds on a KV-1S (20 and 200 respectfully) you can see the merits of it. For my SU-26 I load about 50% gold or 75% gold depending on if I'm playing Pubs, Medium Tank Companies, or Junior Tank Companies.
• AP : Your regular AP round but with crazy pen and damage. It is mostly only useful with high accuracy artillery like HEAT since it does not splash. I load a few (4ish) in my Obj.212 since I have shell room while I don't load any in my S-51 because of its very limited shell count and accuracy. However when those hit you're pretty much killing anything in 1 to 2 shots.

TL;DR

1. About a 66% standard, 33% gold, and 1% HE is a very effective split.
2. HE or Gold rounds should be used to reset base. You do not want to lose because of a bounce. on that 99% captured base
3. Gold rounds have different tracers
4. Only load gold rounds in tournaments, I bet you the other team will have them loaded.
5. Even though they are expensive, you don't have to use them. But having them will definitely help you.
