[QUOTE="Mikecr, post: 1938674, member: 1521"] Wait a minute, Berger says: "it’s better to true MV 10% under transonic"? The only way to measure transonic muzzle velocity is with a transonic load. Perhaps with a cartridge for a suppressed gun. If you meant downrange flight times all the way out through transonic, that sounds like a good thing [U]for[/U] [U]Berger[/U] to setup & do. I'll repeat again for everyone else; Do not LIE to your software. For every input that you actually know, enter the truth. For good bullet path prediction you need to know bullet BC, the air density standard that BC is based on, your local air density parameters, your muzzle velocity, and your sight parameters. [/QUOTE]
