Berger twist rate calculator.

Any imperfection in the bullet jacket, balance and alignment will be exacerbated into dispersion to an extent proportional to twist rate. In other words, the faster the twist rate, the larger the potential group size. This principle is what's driven bench rest shooters to slower twist rates. Naturally, slower twist rates can't stabilize ...Elite Hunter Rifle Bullets are identical in construction, shape and performance to the Berger Hybrid Target series, except they utilize a thinner J4 Precision Jacket for rapid expansion on game animals.
