One of the 6.5 JDJ barrels has taken more deer than any of the other barrels combined. I purchased it back in the 90's, and it became my go-to gun. If I had to keep only one barrel, I would probably pick the 338 JDJ #2. I have been really impressed with it's power and accuracy. The surprise cartridge has been the 270 JDJ based on the 225 Win. The 130 grain Nosler B-Ts work really well and you can get over 2400 fps with them. Of course I'm not done collecting them!
