I also have a kimber mountain ascent 7mm. I have no problem cutting the same hole at a hundred with my load and it did not take long to come up with it. Pretty sure it's one of my favorite rifles I've ever owned.
Actually it wasn't hard to find bad reviews there was quite a few really. But hey there was a lot of bad reviews on the kimber mountain rifle I bought also and after shooting it I kinda beg to differ. Easily shoots sub moa.
