I'll add one caveat to the above....watch for signs of pressure as you work the load up. Don't just focus on what the chrony says for velocity.
Some powders will get you to that 2650 fps, but their burn curve may do so with excessive pressure.
There are so many variables in primers/powder/temp/guns (headspace, etc), brass (thicker making for less internal volume that drives up pressure), that watching for signs of excessive pressure, as you work up, is good adivce.....even with loads from manuals, or that work in someone elses rifle.
