Small change, huge results
The research is clear – changes in humidity will alter the weight of powder a seemingly meager 1%, while also causing a massive 200 ft/s shift in muzzle velocity.
Too dry and it becomes unsafe from increased pressure.
Too wet and you lose velocity.
The CAP prevents this by maintaining a consistent relative humidity for your smokeless powder, regardless of the climate conditions of your region.
