I should keep my mouth shut but, BSA been going through real azzhole syndrome lately. In a way though gruff as it is he’s correct. Sometimes the numbers lead you down into a rabbit hole that doesn’t lead to wonderland.

This was going to be in a different post but it’s quite fitting here. Yesterday I was doing a test on brass weight variables vs group. Again Cooper 21 223, Oehler 35P.

This group had everything going against it, random case weights of 95 grains to 100 grains. 2 different 556 cases of Norma and Federal. Now to really randomize it I loaded 3 different primers, Fed GMM, REM 7 1/2 and CCI standard.
The only thing common was powder charge and bullet. Well I removed the crimp also.
The numbers for 10 shots were not good.

Average 3252
ES 98
SD 32

Small group of the day. The numbers don’t support the results. Don’t get hung up on the numbers.
