Jimmy- a couple of thoughts for you to chew over, while we wait for the seasons to start...
Are you running a chronograph?
I'd try it again as well and see if it truly dropped one inch and if so it has to be the speed diffs/
Was it with the same lot of powder that was used in the summer testing?
Just some thoughts, also a quick question. I've always considered Ga to be a warm summer state and still pretty warm in the fall hunting time. Seriously, what temps do you run normally in the fall season?
Many thx
Dober
