First, Kimber rifles don't have an accuracy guarantee. Second, if they were "all over the place' at 25 yards, it wasn't the ammo. Loose mounts, bad scope, or terrible shooter are much more likely the culprit. At 25 yards, pretty much any ammo will shoot decent. No offense, but if you're working a lot to get most of your rifles to shoot 1.5-2" at 100 yds, something is off. On the other hand, if you're just picking a load, trying it, and being content to with those group sizes, that's another story. Most any rifle of modern manufacture and factory ammo will shoot around 1-2". It didn't used to be that way, but with advancements in bullets, powder, firearms, etc. It's pretty much the norm these days.
