An unfired .25 Auto bullet is about .251. It will be pushed thru a barrel slightly smaller in diameter than that. Each groove is ABOUT 1-2 thousandths of an inch deep. So a barrel with an even number of lands and grooves would have a barrel where bottom of groove to bottom of groove (your red line above) would be 2-4 thousandths greater than top of land to top of land (blue line above).

The number, shape, depth and width of the groove in rifling will vary from caliber to caliber. For instance, not all grooves are square- some look like a triangle.

What we have here is... failure- to communicate.

different makers use different rifling depth and twist rates. Within a single maker there can be large variances in dimensions. The only way to know is to slug your barrel and measure
In life, strive to take the high road....It offers a better field of fire.

Manufacturers have experimented with all sorts of rifling, but to this day none has been proven fundamental to accurate shooting.
