JROD, The "3" setting on the V-Plug is pretty equivelent to the "1" setting on the factory plug. Go to our site and view the comparison pics. You will use the 1 and 2 setting on the V-Plug for more potent ammos such as some bucks, slugs, and 3 inch.
Ok so its working pretty much the way its suppose to and the lower settings are for higher power ammo. Good to know, as i said im happy with the plug i like not needing a tool to adjust. thanks for the responce
