WEAPONx RELOADSOUND2
If WEAPON_RELOAD_TIMING is enabled in the WEAPONx_FLAGS bitfield, WEAPONx_RELOADSOUND2 is the second sound to be played in the weapon's reload sequence. WEAPONx_RELOADSOUND1 is the first.
All weapons have this value set to INSERT_CLIP by default but only WEAPON 1 (the pistol) utilizes it.
