BPI now offers proof testing for your shotshell loads. Our new testing service will help you evaluate the safety and performance of your hand-loads, providing you with reliable data and peace of mind. To ensure accurate results and the safety of our technicians, we have established the following guidelines: 

•  Submission Requirements: All loads submitted for testing must include a complete written description, detailing all components used (including manufacturer and materials) and anticipated results. You must send in exactly six shells per lot: five for ballistic testing and one for dissection and component analysis.  Proof of paid invoice, or order number, must also be included. If you would like to test more than six shells of the same load, please order a second testing service. Include the additional six shells and a note clarifying that both lots are identical.
• Shipping: For safety and compliance, all ammunition must be shipped via UPS Ground or FedEx Ground and be properly marked with the mandatory "Limited Quantity" shipping label.
• Testing Exclusions: We only test smokeless powder loads. We cannot accept factory-loaded or industrial-type ammunition, destructive devices, or loads using black powder, black powder substitutes, or brass shotshells.
• Lab Discretion: The final judgment of a load's fitness for testing is at the sole discretion of our lab personnel. We reserve the right to refuse to test any load. If a test is initiated and the first shot exceeds 25% of the SAAMI Max Average PSI, the test will be terminated, and testing fees are not eligible for refund.

Ammunition Requirements:

• We only test shotshells. We cannot accept any ammunition shorter than 2 inches.
• We do not test 8ga or 32ga shells.

BPI is committed to providing you with a high-quality, reliable testing service. Use reliable loading data and credible sources when preparing your loads for submission. If you have any questions, please contact our testing team.
