This is the sound files i use exclusively for .50 cal HMG in BF2.
I've had this file for so long i can't remember if i made it or i got it from somewhere. Either way its my favorite for the HMG M2.
Copy the sound folder in client/weapons/stationary/hmg_m2hb and save it in case you don't like this. Overwrite it and enjoy.

what impact effects are you using?
That's the proximity ammunition. It's in the add-on section. Just probably really far back.
good one
