Dry firing - good or bad?
Here is some info from Andy Webber of Armament Technolgy reagrding some questions which have surfaced in the past.
1) Dry firing: On centerfire bolt action rifles, little damage results
from regular dry firing; especially with cock-on-opening rifles such as
most modern types. What does cause damage (to Remington 700's anyway) is
slamming the bolt closed on an empty chamber on a regular basis. By doing
this, the primary extraction camming surfaces slam into one another before
they are rotated to produce sliding angular (camming) contact. This raises
a burr on
both the receiver and bolt handle camming surfaces. My advice is to close the bolt gently on an empty chamber, and just raise and lower the bolt handle to cock the action each time you wish to dry fire. The benefits gained by the marksman by dry firing, with respect to trigger control and familiarity of the human interface with the rifle, are many. From my discussions with *very* accomplished Service Rifle marksmmen, I have developed the opinion that for positional shooting (ie: service rifle standing, kneeling, sitting) dry firing at an appropriately-sized target can be more valuable practice than live shooting.
