Kimber and Long-Range in my opinion do not belong in the same sentence.

Less than two months you started a thread asking advice about starting long range shooting, and now you are giving it?
Im a fast learner 😀 It saves on banging ones head against the wall needlessly and painfully for many years. Im fairly certain 6mm dasher is not a factory Kimber chambering. Ive read enouph of your posts to see you are likely very adept and knowledgable concerning long range. Likely knowledgable enouph to recognize that a kimber factory spout is none other than short range fodder!

Reading and asking is a great way to learn, but there's no cheating spent primers, and no shortcut, either.
