RE: Nicest Sounding Cartridge
Loudest and by far the most obnoxious gun Ive heard was a barrett m82a1 with cheap south african 647gr ammo(guess the guy couldnt afford to load for it after he sunk the 9 grand into it). It was a beast. The noise and concussion shook the ground, shook the roof over the firing line. My girlfriend was setting in the car 20 feet behind the shooting line and it shook the car!! A word of advise, do not stand in direct line with the ports of the muzzle brake. I knew that beforehand, but the ole boy that didn't sure got a wakeup call.
Interestingly, the BMG was a *****cat to shoot and because of the brake it was RELATIVELY quiet, concussion was still very obvious.
Nicest cartridge to shoot is a 44 special out of my SBH 6gr red dot 310 gr SWCGC.
