I agree with your answer. But that does not answer the question.If you are new to long range shooting and reloading, I think you need to skip tuners for now.
Focus on making quality repeatable reloads, shooting fundamentals, and learn internal and external ballistics.
Adding another variable that shifts POI and group size is too many variables to play with at the beginning of this journey.
I dont know how good I need to be.I shoot nearly everyday for the last 14 months. I was able to retire pretty young. The range I shoot at is 5 minutes from my house.It currently only has a long distance of 620 yards. The best Ive been able to accomplish in a 5 shot group at 600 yards in 5 inside a one inch bullseye with my 6.5 Creedmoor and my 6.5 PRC. We are trying to get the range to put in a 1000 or 1200 yard range.We have over a 2 mile stretch. Its wooded currently. Our CEO said if we get enough members wanting it we might get it.Im working on it.,
As to reloading.Just started last June...So Im just learning.I am trying to buy the best dies I can.
Thank you for your reply.
