Thanks, George. My infernal machine (computer) is being tempremental and won't let me look at anything on that link right now, don't ask me why! Which book was the Whitworth reference in?

Yes, I'm fascinated at the concept of a rifle from the muzzle loading era which can shoot a bullet with a workable ballistic coefficient. He got that 1 turn in 20 inches as the best by making a bazillion barrels and varying the rifling all the way from 1 turn in 1 inch on out to 1 turn in 70 inches or something like that! After shooting them all, 1 in 20 was best. Musta been some machinist, huh?
