Our Process Is Designed To Ensure Quality And Consistency
Our Match-Grade Brass rifle casings are manufactured on a new, state-of-the-art case line which uses cutting-edge technology to produce some of the most precise and consistent casings on the market, but we are still committed to ensuring the quality of the product our machines produce. To do this, we follow a very thorough inspection process that we've outlined here.
1. Cup Inspection
Visual Inspection
New brass cups are inspected visually for imperfections.
Dimensional Measurements
Dimensional checks are performed on the new brass cups.
Weight
The weight of the brass cups is verified.
Composition Analysis
The chart below displays the metallurgical composition of the brass cups.
| Copper | 72.8000% |
| Zinc | 27.1000% |
| Nickel | 0.0210% |
| Lead | 0.0081% |
| Iron | 0.0075% |

2. In-Process Inspection
Visual Inspections
Drawn brass cups are visually inspected for imperfections.
Dimensional Measurements
Drawn brass cups are measured to confirm proper dimensions.
Wall Thickness
The thickness of the wall of the drawn brass cup is measured verify accuracy.
Hardness Testing
The hardness of the drawn brass cup is measured to ensure quality.
Grain Structure

3. Batch Final Inspections
Casing Exterior Dimensions
The exterior dimensions of the casing are measured to verify accuracy.
Primer Pocket Measurement
The primer pocket is measured to ensure accurate manufacturing.
Weight
The cartridge is weighed to verify manufacturing specifications.
Internal Volume
The internal volume of the cartridge is measured and verified.
Webbing Thickness Measurement
A technician confirms the proper thickness of the cartridge’s webbing.
Neck Concentricity
A technician verifies the neck concentricity of the cartridge.
Casing Hardness
A technician measures the hardness of the casing to ensure safety.
Internal Pressure Testing
The casing’s maximum internal pressure is tested to ensure safety.
Function Testing
The casing is tested in a firearm to verify functionality.
Casing Dissection for Internal Dimensions
A technician dissects the final case to allow him to verify the internal dimensions.
Residue Testing
Casings are tested to verify they have no residue after manufacturing and washing.
