Overview

Built for hunters assembling their own loads, this 30 caliber 180 grain bullet is designed to combine controlled expansion with weight retention. Its open pocket under the polymer tip is intended to initiate expansion on impact, while the tuned ogive and boat tail design support stable flight and accuracy. The construction uses a special lead alloy surrounded by a tough copper jacket, and the product is sold as a component bullet rather than loaded ammunition. For load development, consult a reloading manual or powder manufacturer data before use.

Considerations & Trade-offs

This is a component bullet, not loaded ammunition, so it requires compatible reloading components and published load data before use.
The 180 gr. .30 caliber design is purpose-built for hunting applications, so it is not a general-purpose choice for every .30-caliber setup or use case.
The hollow point and polymer-tip construction are intended to promote expansion, which may be a trade-off for shooters prioritizing minimal terminal upset.
Performance depends on matching the bullet to an appropriate load and rifle; the product description directs users to consult a reloading manual or powder manufacturer data.
