tangent ogive cylinder

The majority of current match bullets employ a tangent ogive design. This profile is specifically optimized to determine pressure distribution along the centerline at supersonic speeds (Mach numbers ranging from 1.25 to 6.75). Key dimensions include bullet diameter (D=1.125), nose length (L=3D), nose radius (R=9.25D), and shank length (7D). The tangent ogive equation is given as sqrt((P^2-(L-x)^2))+R-P, with P calculated using the formula P=(R^2+L^2)/(2*R).
