Pros

  • Hollow point design with scored nose cavity for varmint and predator use.
  • Flat base bullet profile included in the product specification.

Considerations & Trade-offs

  • Available in two bullet weights, so you’ll need to confirm the 58gr or 72gr option matches your rifle setup and intended use before ordering.
  • The listed twist-rate guidance is 1:12" or faster, which may limit compatibility with slower-twist barrels.
  • The design is described as a hollow point with a scored nose cavity and thin tapered jacket, so it is purpose-built for varmint and predator use rather than general-purpose shooting.
  • Ballistic coefficient and sectional density differ between the two weights, so external ballistics will vary depending on which version you choose.
