There is a bug in the twist field when switching to metric units. With SAE units, twist is to be entered in inches per one revolution (for example 7).
After switching to metric units the header says “calibers per revolutions.” 7 inches would be equivalent to 22.7 calibers for a .308 bullet. But the field shows “118” which is obviously wrong.
Metric use normally is giving the twist in millimeters. 7″ is 178 mm.
