How do I make new "cannon" type to give individual range etc?

[19DScout]

I have read the "make your own artillary unit tutorial and followed the step with the exception Im not making new pictures or animations just trying to give my cannon it's own "cannon" (ex the 24 Pounder Guard cannon) seperate statistics than the normal 24lber.

I followed the guide giving it the same name in: gun_types_table, gun_type_to_projectile, animated LOD tables (model path), warscape animated tables (texture path), and unit stats land. Basically i'm just trying to make it alittle better IE slightly more range etc. and I think that I've edited/created the proper files for that but can't seem to get them to apply to the unit.

I have changed existing cannons so I can do that fine just can't figure out how to apply a totally new cannon stats to this cannon.

Any help would be greatly appreciated.
