When fire lapping, what is recommended to do between each round?

When fire lapping a firearm's bore, it is crucial to clean the bore thoroughly between each round. Fire lapping involves firing specially coated bullets through the barrel to smooth out imperfections and enhance its accuracy. After each shot, residue, lead, and other particulates accumulate in the bore, which can interfere with the effectiveness of the lapping process.

Cleaning the bore thoroughly removes these contaminants and allows for a more consistent, unobstructed surface for the next lap. This ensures that each round's effects on the bore are not muddled by previous fired bullets' residues, thereby maximizing the results of the fire lapping process.

Options that suggest soaking the bore in oil, brushing it with a cleaning rod, or waiting for it to cool do not address the immediate need to clear away debris and maintain the effectiveness of the lapping process. While other maintenance steps may be important in different scenarios, thorough cleaning between rounds is specifically vital during fire lapping to achieve the desired improvements in accuracy and barrel finish.
