    2012-12-18 · – The guide rod adds extra weight to the muzzle, making the slide – and with it, the entire handgun – heavier, allowing the shooter to control the muzzle flip much better. The recoil energy that moves the slide can be changed by modifying the mass of the gun, possibly making the shooting more accurate, by allowing the shooter to get back on the target faster.

In this case of observations, one of the bar-code staves will be in the direction of sun and the other will be opposite this direction, so the resulted accuracy of leveling will not be the same.

    When we go about the task of determining the accuracy of a method, we are focusing upon the identification and elimination of systematic errors. Don't be misled by the statement that 'good precision is an indication of good accuracy.' Too many systematic errors can be repeated to a high degree of precision for this statement to be true.

    2013-2-9 · If you do not have the proper guide to keep it straight, the rod will wear against the inside of the barrel as you pull it back and forth. This can wear the throat/leade of the barrel where the chamber ends and the rifling begins. This is very bad for your barrel and accuracy. A warped rod will bow and also wear on the barrel further down.
