Compat R3F : AtragMx presets Scope Base Angle

• update the AtragMx presets' Scope Base Angle for all rifles :

From the ACE3 Slack by @ulteq

I have an idea how you could calculate it yourself with the current ace3 release.

1. Load your custom profile (with an arbitrary scope base angle) into the ATragMX
2. Open the Gun/Ammo Page and close it with the 'Done' button.
3. Execute copyToClipboard Str(ace_atragmx_workingMemory select 3); into the debug console

This should dump the correct scope base angle for the current profile into the windows clipboard.

As usual, many thanks for your help. :)

• fix my splendid mistakes to the J4,J8 and J10 ACE_ScopeAdjust_Vertical.
• update the CfgMagazines according to the new Gunlist.
