My model 700 loves the core lokt. At 100 yds i had four shots touching and two an inch away. Which i know was my fault. I hit a bull elk at 390 yards and it did a good job on that. They have taken out 6 deer to date and not one failure. They are all i shoot because they are cheap and shoot good in my gun. Like mossyoak said, with mass production you are goin to have failure. It just happens. Especially when you buy a box of ammo that is $15 a box. Remington also makes a more expensive ammo. I dont think one problem is enough to say that Remington ammo is junk.
