Enrollment Deadline: 15 March 2026

Participants will compare and identify firearms evidence such as bullets and expended cartridge cases.

Sample Description: Either expended bullets or expended cartridge cases. Samples are different from those used in Test 5261, and the evidence type is alternated yearly between both tests to allow participants to receive both types of firearms evidence in one year by ordering both tests, or to stay with the same test year after year and receive both evidence types every two years.

Samples ship in October.

This test is included on CTS' Scope of Accreditation to ISO/IEC 17043.
