1. A projectile comprising: a body having an axis;a nose comprising a frustum and a meplat disposed substantially orthogonal to the axis and along a meplat plane, wherein the meplat is bounded by a substantially square perimeter edge, and wherein the frustum comprises four curved surfaces extending from the meplat, each of the four curved surfaces intersects the meplat plane at a substantially orthogonal angle, and each of the four curved surfaces intersects one another at an intersection curve; anda substantially round collar, wherein each of the four curved surfaces terminates at the collar. 2. The projectile of claim 1, wherein the body comprises a body tail surface disposed opposite the meplat, and wherein the nose extends from the meplat towards the body tail surface. 3. The projectile of claim 1, wherein the body comprises a body ogive radius and the collar comprises a collar ogive radius substantially the same as the body ogive radius. 4. The projectile of claim 1, the body further comprising a neck disposed between the collar and the body, wherein the neck comprises a diameter less than a diameter of the collar. 5. The projectile of claim 4, wherein the body defines a groove reference curve spanning from the body to the collar, wherein the groove reference curve is identical to the body ogive radius. 6. A projectile comprising: a body;a nose formed monolithically with the body, wherein the nose comprises a frustum and a meplat, wherein an outer edge of the meplat is at least partially defined by a plurality of corners having a plurality of straight sides extending therebetween, wherein the frustum comprises a plurality of curved surfaces, and each of the plurality of curved surfaces extends from a respective straight side of the plurality of straight sides, wherein each of the plurality of curved surfaces intersects the meplat at a substantially orthogonal angle, and wherein each of the plurality of curved surfaces intersects one another at an intersection curve that extends from a respective corner of the plurality of corners; anda collar, wherein each of the plurality of curved surfaces terminates at the collar. 7. The projectile of claim 6, wherein the frustum comprises four curved surfaces extending from the meplat. 8. The projectile of claim 6, wherein an outer edge of the collar is at least partially defined by a circular outer edge. 9. The projectile of claim 6, wherein the projectile comprises a total projectile length and the nose comprises a nose length of about 25% to about 35% of the total projectile length. 10. The projectile of claim 9, wherein the nose length is about 27.5% of the total projectile length. 11. The projectile of claim 9, further comprising a neck connecting the body and the nose, and wherein the body and the nose define a groove substantially surrounding the neck. 12. The projectile of claim 11, wherein the neck comprises a neck length of at least about 10% of the total projectile length. 13. A projectile comprising: an axis;a total projectile length measured along the axis;a nose comprising a collar, a frustum, and a meplat, wherein the frustum comprises a plurality of curved surfaces, and each of the plurality of curved surfaces intersects the meplat at a substantially orthogonal angle and terminates at the collar, and wherein each of the plurality of curved surfaces intersects one another at an intersection curve that extends between the meplat and the collar;a body having a body tail surface, wherein the body and the nose are monolithic; anda neck connecting the nose and the body, wherein the neck comprises a neck diameter of about 80% of a diameter of the collar, and wherein the nose and the body define a groove therebetween wherein the groove comprises a groove length of at least about 10% of the total projectile length. 14. The projectile of claim 13, wherein the meplat has an angular outer edge. 15. The projectile of claim 13, wherein the body comprises a body ogive radius and defines a reference curve spanning the groove, wherein the reference curve further extends from the collar to the axis, and wherein the reference curve comprises a reference curve radius identical to the body ogive radius. 16. The projectile of claim 15, wherein the nose is substantially contained within the reference curve. 17. The projectile of claim 15, wherein the nose is contained within the reference curve. 18.
