This is like comparing a 38 Special with a 44 Magnum ! The 375 JDJ is an awesome hunting round - but, it is MUCHO overpowered for silhouette. A lot of your better Standing category are gravitating more and more to the "lower recoiling" rounds, such as 270 Max, 30-20, 30 Carbine, 300 Whisper, and so on. As an International class shooter, I shot my best scores with a 30 Carbine and a 357 Mag revolver. I think that the 270 Max could be the perfect gun for standing - good knock-down and light recoil. The 375 JDJ is too much of a good thing, unless you enjoy recoil and noise. It is an awesome round - I have shot one in a hunting set-up and I was mucho impressed - but, would not want to shoot a silhouette match with it !
