Drawing and reloading sounds play at max volume for all players in multiplayer regardless of distance (If within the same chunk).
Firing sounds are normal (Decreasing with distance).

Tested in tac-a-0.3.10.2-1.18.2

Modpack with no other gun mods, however ebeddium-0.3.0 and lazydfu-1.0 is included.

This issue will be fixed in version 0.4.0, or later, anyway, we are working on fixing them
