With my retirement date finally set (I chose 5th of July so I can celebrate my independence from work every year with 4th of July ), I have taken some time to reflect over work that's been done for accuracy testing as outlined in this post - https://www.thehighroad.org/index.p...-and-discussions.778197/page-10#post-10966692
After reviewing many threads and posts by more experienced THR members on accuracy testing, especially when they posted that sample size is too small to make a definite determination (Yes Walkalong, sample size must be large enough to matter ), I increased my shot group size from 5 rounds to 10 rounds.
Well, after doing some extensive sorting and range testing various 22LR ammunition, I am beginning to believe even 10 round groups may not provide all the information as to true accuracy (jmorris and Bart. B, you were right ).
Shooting 20, 30, 40 and 50 round groups opened up the group size with "occasional flyers" becoming more regular - https://www.thehighroad.org/index.p...weight-and-rim-thickness-for-accuracy.850634/
As reference, this article conducted 50 round (entire box of ammo) shot group testing with Ransom Rest at 25 yards - https://www.ssusa.org/articles/2019/1/18/38-different-9mm-loads
Compiled 50 round group sizes shown in this table is quite interesting (Not what I expected) and I will start doing 20-50 round shot group testing at 25 yards in the future for evaluating accuracy of loads - https://d2mhjaozymokej.cloudfront.net/media/1540004/table-1-extreme.jpg
