LEAD-FREE BULLET FOR USE IN A WIDE RANGE OF IMPACT VELOCITIES
First Claim
1. A bullet comprising a lead-free body having a tail section, a nose section having an ogived outer surface and a forward terminus, an opening at the forward terminus, the opening having a first-cross sectional dimension, and a cavity in the nose section extending rearward from the opening to an intermediate section of the body, wherein the cavity includes a forward sidewall that has at least a generally frusto-conical shape extending from the opening to a second cross-sectional dimension, the forward sidewall converging rearward from the first cross-sectional dimension to the second cross-sectional dimension, and a rear sidewall contiguous with the forward sidewall and extending directly from the second cross-sectional dimension to a third cross-sectional dimension, the rear sidewall diverging rearward from the second cross-sectional dimension to the third cross-sectional dimension.

Abstract
A bullet comprising a lead-free body having a tail section and a nose section. The nose section has an ogived outer surface and a forward terminus. The body further has an opening at the terminus, and a cavity in the nose section. The cavity extends rearward from the opening to an intermediate section of the body. The cavity includes a forward sidewall having at least a generally frusto-conical shape that converges rearward from the opening to a transition area. The cavity further includes a rear sidewall extending rearward from the transition area at a different angle than the forward sidewall.

- 11. A bullet comprising a lead-free body having a tail section, a nose section having an ogived outer surface and a forward terminus, an opening at the forward terminus, and a cavity in the nose section including a forward sidewall extending rearward convergently from the opening toward a transition area, the body having a first wall thickness at the transition area, skives in the forward sidewall, a rear sidewall contiguous with the forward sidewall and diverging rearward from the transition area, and a cavity end, the body having a second wall thickness at the cavity end, the second wall thickness greater than the first wall thickness, wherein the forward sidewall and the rear sidewall are configured to form petals upon impact in animal tissue that remain with the body at impact velocities of approximately 1,800 ft/sec to approximately 3,200 ft/sec.

20. A bullet comprising a lead-free body having a tail section, a nose section having an ogived outer surface and a forward terminus, an opening at the forward terminus, the opening having a first-cross sectional dimension, and a cavity in the nose section extending rearward from the opening to an intermediate section of the body, wherein:
-
