Accurate No. 5 «2K | 4K»

The Accurate No. 5 was designed according to the , which states that the scale of measurement must be in line with the axis of the measured object. Unlike cheap calipers or flat anvil micrometers that could introduce cosine error, the Accurate No. 5’s linear guide system was so finely lapped that repeatability was astonishing. A skilled operator could detect variations as small as 50 millionths of an inch (0.00005")—a level of precision that rivals many modern digital sensors.

When used at optimal pressure levels (typically the upper 70% of load data), it is known to burn very cleanly. Common Calibers accurate no. 5

Reloaders often compare Accurate No. 5 to other "intermediate" burners. If Accurate No. 5 is unavailable, popular substitutes with similar applications include: The Accurate No
