wow that is some extreme clean bore fliers... if one was at the same target. And I agree 5 inches left is a big miss. I have two rifles that when they are dirty they are great. But you try and make them shoot clean, they will miss ever time. One is an old Traditions side lock. On round ball the clean bore is often 3 inches off. The other is a rather new LK-93. On a clean bore it is always 2 or more inches off. BUT I agree, 5 is extreme. I would foul that horse too...
