Yea, I downloaded TwinBoom's pack. Perhaps that's the cause?
Actually the reason I asked is because maybe you could ask TB or whoevers sound pack you happen to be using if they can lower the sound level on the weapon of choice.
Or if they can direct you,and me to the proper sound file because this issue comes up often,thats why I knew the 8 in guns were in the explosion sounds.
If you happen to find the solution please post it so I can share it with others.
TIA.
