I have a buddie that can replicate the sound that "Bo Whoop" made. Several years ago when we were shooting hi-power matches we bought some surplus powder known as BW-36. I loaded some for my 308 and my bud loaded some for a '06 Garand. My loads performed OK, but when he shot his '06 the report was a long "Bo Whoop" accompanied with a huge muzzle flash. Come to think of it, it was more of a BuhhhhhhhWoooooooommmmmm!!! He gave me the remaider of his powder,

Dodging lions and wasting time.....
