CJ ( Chris Jamison ) is out here visiting his dad and we have been testing his new 6.5/284... later this week were gonna go after some LR pd's gonna try to get both of us in the 1K club!.. anyway .. I ran some J4 bullets through the 308 and WOW very accurate!! I shot a .496, 15 shot group ( CJ witnessed it! ) I was wondering if anyone has cut any in half to see how thick the jackets are or better yet anyone taken any game with em??
