Tangent Ogive
A bullet nose profile whose curve blends smoothly into the shank, giving a forgiving design that tolerates a wide range of bullet jump.
A tangent ogive is a nose shape whose defining arc meets the bearing surface tangentially, so the curve flows into the cylindrical shank without a visible break. This smooth blend produces the classic rounded spitzer profile seen on most traditional rifle bullets. The geometry is easy to make consistently and tends to engage the rifling squarely.
The practical virtue of a tangent ogive is forgiveness. Bullets with this profile generally shoot well across a broad span of seating depths and jump to the lands, which makes load development simpler and more stable. The tradeoff is a slightly lower ballistic coefficient than a sharper secant shape of the same weight, a price many shooters accept for the easier tuning.
