It can be kinda annoying to have to manually edit the load-out to include the practice bombs prior to each mission, right?

It's easy to create a custom load-out, and then edit the mission to include your custom load-out by 'default' for that particular mission.

To create a 'BDU-33' low-drag practice bombing load-out, just go to the Objects/Aircraft/T-6A folder and open the T-6A_LOADOUT.ini file in Windows Notepad.

Copy the [Attack] load-out and edit it to include the BDU-33 practice bombs. I kept the machine-guns and drop-tanks in my loadout so I can loiter over the range and have some strafing practice too:

[BDU-33]
Loadout[01].WeaponType=SUU11
Loadout[01].Quantity=1
Loadout[02].WeaponType=SUU11
Loadout[02].Quantity=1
Loadout[03].WeaponType=Tank_PC-9
Loadout[03].Quantity=1
Loadout[04].WeaponType=Tank_PC-9
Loadout[04].Quantity=1
Loadout[05].WeaponType=BDU-33
Loadout[05].Quantity=1
Loadout[06].WeaponType=BDU-33
Loadout[06].Quantity=1

Note: the 'name' of the weapon comes from the line 'TypeName=BDU-33' in the BDU-33_data.ini file (in the Objects/Weapons folder).

Now you can go to the Missions folder and edit the .MSN file (in Notepad again). Find the line:

Loadout=RECON

... and change it to:

Loadout=BDU-33

Restart the game and mission and - viola - practice bombs by default for the mission. You can customise your other missions likewise. For mine, this feels a bit more realistic to me when firing up a mission - it's not like the pilot normally gets free reign to pick any weapon he likes from his nation's arsenals - so I like it a lot this way!

Hope it helps someone else too.

P.S. I copied the .MSN folder for this mission and renamed it 'Training Mission #05a - Manual Bombing'. I gave #05a a custom high-drag BDU-48A loadout, so I can practice low-level bombing too (in separate missions).
