I copied some loads I shot last year and noticed I have much more variation in speeds and most where lower.
last year 5 shot group: 2338, 2345, 2341, 2343, 2334
last week 3 shot group: 2280, 2147, 2325
as far as I know, everything is the same. its even the same canister of powder. The only difference is last year I was using once fired brass and now I have 5 firings on them. It was also a windy day, so I guess the chronograph could have been shaking some, maybe???
Thoughts?
