A quick net search got me this link. https://bisonballistics.com/articles/opt...for-rifles. The Radial Standard Deviation method would be great, those that use it please comment on how you like it and how you record the data to compare your loads.
My Simple Minded method is to use a clear template with circles lines like a target, say .5 inch center and .5 between circles and scored like a target, 10 points for each shot inside the center circle, 9, 8, 7, etc for shots that land in the corresponding outer circles.
Place the template on a five round group for max score, record the total for easy comparison.
Suggestions? Helpful criticisms? Better ideas? All welcome!
Hi Lemonaid, hope you are ok. I read the very interesting article as per your link and I thank you for sharing it. It appears that 7 shots group is a good compromise when seeking for the best ammo/reloading/rifle matching. What I am not able to understand is how many groups ,for a any ammo/reloading sample, one should fire in order to get a meaningfull result?
