Identifiable Bullet With Sealed Bore Marker
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for identifying ammunition, such as etching or painting the bullet, often result in poor adherence, inconsistent marking, distortion of weight distribution, and adverse effects on ballistic performance and firing trajectory.
Innovation Solution
A user-identifiable bullet with a bore at the forward end, sealed with a transparent polymeric material, where a marker is placed inside the bore to provide clear identification without affecting the bullet's trajectory, using a method that involves forming a bore, placing a marker, and filling it with a flowable polymeric material that hardens to form a transparent seal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If etching or painting is used to mark the bullet, then identification is achieved, but adherence is poor and inconsistent
Solution Approach 1:
The marker is nested inside a bore that extends through the bullet, with the bore sealed by polymeric material. This nested structure ensures the marker remains securely positioned and consistently visible while maintaining bullet integrity.
Solution Approach 2:
The polymeric material acts as an intermediary substance that fills the bore and seals around the marker, providing consistent adherence and protecting the marker from environmental factors while maintaining identification clarity.
2Reliability
If etching or painting is used to mark the bullet, then identification is achieved, but weight distribution is distorted
Solution Approach 1:
The bore is positioned asymmetrically within the bullet structure, allowing the marker to be placed in a location that provides identification while the polymeric material fill balances the weight distribution to minimize impact on trajectory.
Solution Approach 2:
The polymeric material is selected and positioned to change the physical parameters of the bullet structure, specifically filling the bore to provide weight balance and distribute mass evenly around the bullet axis, thereby maintaining trajectory stability.
3Reliability
If etching or painting is used to mark the bullet, then identification is achieved, but ballistic performance is affected
Solution Approach 1:
The bullet is segmented into distinct functional zones: the marker region inside the bore for identification, the polymeric material fill for structural integrity and weight balance, and the remaining bullet body for ballistic performance. This segmentation allows each component to optimize its function without compromising the others.
4Reliability
If etching or painting is used to mark the bullet, then identification is achieved, but firing trajectory is affected
Solution Approach 1:
The polymeric material fill within the bore acts as a counterweight mechanism, balancing the weight distribution around the bullet axis to compensate for any asymmetry introduced by the marker placement, thereby maintaining stable firing trajectory.

AI summary
The invention relates to an identifiable bullet and methods for making an identifiable bullet. In one embodiment, the bullet has a generally circumferential body that tapers from a rearward end toward a forward end. A generally circumferential bore extends from an orifice on the forward end into the body at least part of the way between the forward end and the rearward end. The end of the bore opposite the orifice includes a polymeric material support surface. A polymeric material is placed between the polymeric material support surface and the forward end. The polymeric material may include a user identifiable marker for allowing a user to identify the bullet when viewing the forward end. Alternatively, the polymeric material may cover a user identifiable marker and seal the user identifiable marker in the bore. A user may identify the bullet by viewing the marker from the forward end of the bullet.
