Now the new American TD line with turrets have been introduced I decided to try this line, I used some free XP to go from the T1 Cunningham directly to the M8A1 so I already had the turret-TD.

I have the tracks upgraded and the 57 MM gun, which has 110 pen and 75 damage and fires 23.86 rounds per minute (1790 DMG/Minute)

While the 75 MM AT L/50 does 101 pen and 110 damage with 14.29 rounds per minute (1592 DMG/Minute) and its even less accurate!

Now I personally don't know why I would go for the elite gun (which is the L/50) besides it's useful for the Hellcat.

Do I miss smething?

I play the top 75, it is more accurate than the stats say, last game I was able to score 4 hits on a moving T50 in a row at 300m, its penetration is less but its more than good enough for the tier.


I may play the 57 some more for a better comparison though, but I am pretty well sold on this gun.

last game using the 75-L50 962 XP no bonus and non premium 5 kills 6 damaged

Thanks for the input.

What is more important for tank destroyers? Damage per second or alpha damage?

Depends on type of TD.

Here, I would go for alpha since M8 is neither fast nor tough enough to survive prolonged engagement.

Both have advantages:
High alpha damage will allow you to shoot less often for a certain amount of damage, so you can stay hidden/in cover a little longer. A higer rate of fire can be very useful when fighting multiple enemies, trying to stop fast scouts, tracking bigger targets for arty and so on.
It also depends on the matchmaking, your own preferences, the guns available for the respective tank and its characteristics.
As the M8A1 isn't a classic "sniping TD" but rather agile and med-like (imo), a higher rate of fire seems more useful to me.
As always:
Try both and see which one works better for you.

Just got my Ace Badge in this. I use the 75mm. It's just useful when you're staring down a KV. The 57 bounces too often, but is a great gun for the T82.

The top 75mm is probably the best choice, at least in my opinion, especially with the inevitable high tier stacks you are going to see.

How does the 57mm bounce too often when it has higher penetration compared to the 75? Isn't that a bit counter-intuitive? I used the 57mm the whole time on the M8A1 and didn't feel like I was bouncing too many shots.

Ace badged with 75mm but prefer the 57, rof and pen win it for me.

I think its the overmatch rule, you see if the caliber of the shell is more than the thickness of the armor you never bounce.

so with low tier armor the 75 would never bounce where the 57 would, even though it has greater pen

Almost. I think you are referring to this one: overmatch
Tbh I'm not quite sure how these are implemented ingame.

Overmatch is caliber/3, with 57 you will never bounce armor under 19mm, and with 75mm armor under 25mm. Basicly not much difference.

Huh. I guess I still have a lot of reading to do when it comes to the game mechanics. I've never heard of that particular mechanic before.
Is the difference significantly noticeable in-game? I might stick the 75mm on my M8A1 and see how it compares to the 57mm.

i just got the 57 mm and love it i think its better for higher tire battles thanks to that bit more pen which means u can damage things like tigers 100mm armour (as long as its not angled) i managed 4 kills and i was near bottom even killed a panther from the front thou he was on 7% thanks to the pen and RoF also pretty accurate and didnt bounce often will have to try out the 75mm but think im gonna stick to the 57mm deff gonna keep this tank its great =]

It's a small, fast td, so think logically - why would u put heavy gun on it, better to stay aggressive and use high rof to annoy other players, for me It was  a miracle, 71% wins

overmatch is more significant a mechanic in higher tier matches like when you have the really big guns like a jadtiger

but I you have a relatively large caliber at a low tier the same rules apply

I would quote from the wiki but the mechanics are being re edited to be in line with the last patch.

but basically if your shell is x3 the thickness of the armor you get penetration no mater what if it Is x2 you get a reduced chance of ricochet and therefore more chance of penetration etc

I haven't played the tank a whole lot, nor had any great games, as yet, but I chose to stick with the 57mm.  It's lighter, so you have better mobility.  It's more accurate and has higher penetration performance.  Every once in a while, I wish I had the 75mm fit, but not that often.

Yeah yesterday i missed the 75mm when i had to stop a stug and another tank. With the 57mm i hit but on short distances only killing count. But in most times i like the 57mm more because i can cause damage on the big boys.  

Hey and when you like the 57mm, try it in SU-85B there it has more Rof/Penetration/Damage its a really Fun-Gun  

Yesterday the M8A1 and SU-85B make me a smiling so much.

It is very simple:
The "57 mm Gun M1 L50" goes: pew, pew, pew, pew, pew, ... .
The "75 mm AT Gun M7 L50" goes : boom, reaim, boom, reaim, ... .

I prepfer a boom, boom gun, a rammer, optics, bino, gasoline, which make it a fearsome opponent in it's MM.

I prefer the 57mm
