Bench shooters chase the rabbit hole.. every time you improve one thing, you have to go to the next variable to make it better…

Velocity mostly comes from pressure…. And leaving the barrel at the same time comes from another type of consistency, and how many, and much vibrations are in the system you are shooting.

Small samples have always had the issues he’s talking about - however, that’s only one of the variables.

With my PRS rifle I can’t find a group that doesn’t cloverleaf at 100 yards these days so I had to move out further, and shoot at sun up to refine my loads more.
