What is a necessary action to take after the fire lapping procedure?

The necessary action to take after the fire lapping procedure is to continuously check the bore for any irregularities. Fire lapping involves using abrasive ammunition to smooth the bore's interior, which can lead to variations in the rifle's accuracy and performance. By checking the bore regularly, you can identify any potential problems such as uneven wear, improper smoothing, or other irregularities that may have developed during the procedure. This vigilance ensures that the firearm maintains optimal performance and helps catch any issues early.

Other actions, like storing the firearm without further maintenance or immediately switching to larger bullets, would not contribute to maintaining the firearm's integrity or performance post-lapping. Rinsing the bore with a chemical solution alone, without ongoing checks, may miss critical evaluations of the bore condition and could overlook necessary adjustments to enhance accuracy.
