So by your estimate, velocity is the sole key to accuracy, since you've mentioned that more than once...
Interesting.....
Wonder then, how I can work up sub MOA loads across a 145 degree change in anualtemperature, using powders considered temp sensitive, change lot numbers, use brass that is not sorted by weight or volume, with bullets that the vast majority of internet gurus consider inaccurate....but I am an example of only one.
Wonder also how Federal Gold Match can be so successful across such a wide dispersement of arms day in and day out, month after month, season after season.........I highly doubt they tweak powder charges at the change of the four seasons.
Simple laws of physics are sometimes very hard for some to grasp...
I'm really curious where he is that he's getting a 145' annual temperature swing and thinks he isn't getting variations in pressures and humidity levels.
Bye the way the ammunition manufacturers can blend their propellants to make them almost temperature insensitive and produce consistant pressures. The blends are never going to released as a handloading component. The closest you'll ever come is to geta manual like the Lyman # 47 which will give you a factory duplication load achievable with available components.
