[QUOTE="youarenotcrazy, post: 138747, member: 555"] If I may interject, Catshooter I like and respect the majority of your posts. I do feel, however, Michael's intentions and your interpretations are slightly off-skewed. I don't feel, using the same barrel, that switching powder/primers yet arriving at the same muzzle velocity will yield different BCs. That said, I don't think that's what Michael meant though, I believe he meant changing those components for an "ever so slight" muzzle velocity change would alter your ballistics. Please do not nitpick the paragraph apart and manhunt for errors. His general idea was SPOT ON and well delivered. Different barrels have different land engagements on the bullet, different frictions and of course sometimes slightly different twist rates (ie, 1 in 10 is not ALWAYS 1 in 10... sometimes 1 in 10.15"...) I imagine that could all make a difference at such a distance, being that they would change the outside structure of the bullet. lol, it's late, and I forgot where I was going now. I do agree with whoever said it, prolly Michael, that ballistics programs need to be calibrated for individuals once you get "out there". To 600 yards everything is close enough, after that to be spot on it will usually involve a little tweaking. For what it's worth, I HATE cool-aid.
