Modified Cartridge Case Over All Length (COAL) Brass have been modified to be used with the Hornady or Stoney Point COAL tool to measure your chambered COAL with a given bullet.
Each piece of brass has the neck uniformed and reamed .001" over bullet diameter. The base of the cartridge is precision machined on our CNC for a clean and correct fit.
Each piece of brass is either brand new, or has been fired, cleaned and properly sized to match the Go Gauge for that cartridge to ensure an accurate fit in your chamber.
These pieces of brass are perfectly executed to offer the most performance out of your COAL tools.
