JD most definitely didn't invent the round but he did trademark the "Whisper" name. There were wildcat .30 cal's based on the .221 fireball and the whole 222/223 series not long after they came out commercially. That was way back in the 50's and 60's. As for him "inventing" the round as a subsonic I don't think that was the case either.....I've seen some evidence of similar or possibly identical rounds used in the 60's and 70's for subsonic use with heavy bullets. What I believe JD did was marketing where the others didn't. On some of the other rounds he claims (or others have claimed on his behalf) to have invented, some are probably his like the 510 whisper and others have obviously been tried before like the 338 1.5 also known as the .338 whisper. The .308 was shortened to 1.5" long ago and used in a number of applications including necked up to .338 and launching subsonics. It was also reduced to 6mm, 7mm and called the 6BR, 7BR and 30BR. Others like the 338 whisper 2 was used before and has been copied since by someone calling it a thumber or something like that....
I guess in the big scheme of things the original inventor seldom gets the credit, the guy who convinces everyone to use it does. The only gripe I've got with JD is that he seems a bit paranoid and hard to talk to unless you're handing him money. On the other hand, if I had a load of idiots like me asking questions I might get a bit crotchity too.
