DAA,,,No offense taken,,,,My comment regarding the harmonics should not have been coupled with the effect on accuracy..Quote:OT, no offense, but the above just doesn't even make sense. Harmonics and accuracy are conjoined twins. Tuning a load is tuning it to the harmonics of the barrel. Change harmonics and the results can't be predicted to be better or worse or not noticeable.I use mine for the sole purpose of establishing velocity as compared to factory loads before starting to concentrate on accuracy....It's possible that my observation was an unintended occurrence from my last range session with it...I'm familiar with the concept of barrel tuning and harmonics...
