Controlled spin projectile

A method for launching a projectile along a trajectory characterized by a controlled spin rate and a substantially balanced forward and axial deceleration including the steps of:

• forming the projectile having a body including a bearing surface and an ogive continuous to and extending forward from the bearing surface and an aerodynamic drag factor upon launching and during flight in the range of 0.100 to 0.250;
• forming the projectile having ratio of a spin rate of the projectile to a forward velocity of the projectile upon launching and during flight in the range of 1.25:1 to 1.40:1;
• and
• imparting a physical feature to a bearing surface of the projectile, the physical feature having a depth substantially equal to 1% the caliber of the projectile and a ratio of a total surface area of projectile to the total surface of the physical feature in the range of to 3.00:1 to 4.00:1 for imparting an axial surface friction upon launching and during flight required to produce a trajectory characterized by a continuously decreasing rate of axial deceleration.

A projectile comprising:

• a body including a bearing surface and an ogive continuous to and extending forward from the bearing surface;
• the projectile including a pre-selected physical feature having a depth substantially equal to 1% the caliber of the projectile;
• the projectile including a relatively low drag coefficient in the range of 0.100 to 0.250;
• and
• the projectile including a ratio of a total surface area of projectile to a total surface of the physical feature in the range of to 3.00:1 to 4.00:1.
