I love everything JDJ, I currently have:

.300 Whisper
.257 JDJ
6.5 JDJ
.270 JDJ
.309 JDJ
.375 JDJ
7 mm #2 JDJ

I used to use the .375 JDJ for everything, but I am planning on taking the .309 JDJ out west for Elk. I love the recoil and it seems to be a little flatter shooting... or maybe that's just me...
