1. A detailed description of the issue you have encountered. It is also important that you describe how we can reproduce the issue, if you are able to reproduce it.

The 37mm M10 cannon does not have a correct rate of fire nor does the HE shell have enough Tetryl filler.

 

2. If applicable, the full name(s) of the vehicle(s) affected.

Everything with the 37mm M10 cannon.

 

3. If applicable, the difficulty setting (e.g. Arcade) in which the issue occurs.

All difficulty settings as this is a issue with the weapon.

 

4. If applicable, an attached screenshot showing the issue, as well the client reply file and the server replay.

Spoiler

As you can see:

• The rate of fire is currently 163 rounds per minute

• The HE shell currently only has 45.00 grams of Tetryl filler

 

5. Attach the Client Log of the session in which the error occurred. If the problem is persistent, attach the latest one available.

See attached.

hi.

 

for the filler, the game does not always give the exact value.

 

The weight is independent of the destructive power of the shell (these are 2 different variables).

I can report the weight to be updated to 45.3g, but I will not go to the 3rd decimal.

 

As per the rate of fire, 165 is the absolute best. Based on available documentation, 163 rpm is slightly lower, but also more often met on the field.

The difference is close to nill and imperceptible.

 

Regards

Even if it does show the correct explosive filler, it's still not correct in the files. On the left is the German 20mm mineshot from the MG 151 (cannonmg15120.blk), note how it goes to three decimal places. On the right is the US 37mm HE shell from the M10 cannon (cannonm10.blk). Note how it does not go to four decimal places like the German 20mm (despite the fact it should, +0.359 or +0.3592 grams).

Spoiler

 

So it definitely would help a little, considering it's gaining 0.359 (or 0.3592 if including all decimal places) grams of tetryl filler.

So other documentation takes precedence over the actual cannon's technical manual? It's not like this change will actually significantly change much, but it's still not right according to the M10's actual technical manual.

The 4 decimals are from KG base.

0.0183 is 18.3 g.

So 45 would be 45.3, but 45.328g would not be in game.

And as I said, the value displayed is a variable. It does not relate to the actual explosive performance. I could myself edit the file and replace the filer type by 'Apple puree', 1 ton, the damage would be the same.

Explosion performance and visual display of explosive type and mass are not linked.

 

For the 165rpm, the manufacturer, best case scenario cyclic rate of fire is in ideal conditions. When loaded in a plane, the entire mechanics and bullet path is different.
