LOP and DAH questions

[Gary Laudermilch]

In my experience the chamber insert lasers are inadequate. The one I find useful is a Robert Louis unit that fits in the muzzle and centers itself. It is not cheap however. While it is beneficial to new shooters I also find it helpful when I switch guns with different stock dimensions. Before going to the range with a different gun a few minutes with the laser beforehand helps immensely. One of my Parkers has 3" drop and requires a gun mount considerably different than others I use. The laser makes transitioning quicker.
