Now part two. I took it out and shot it and it is the worst shooting MKII I have ever fired. I am not NCG but I do decent with handguns but not this one.
I started going through some things maybe causing a problem with the bad accuracy. First thing to always check is the crown. BINGO! The crown was very uneven. I got out my round head brass screw and my 600 grit lapping compound along with my variable speed drill. So I recrowned it and used a eye piece from a 4X Weaver scope looking through it backward makes a good magnifying glass. I thought it needed a little more and that made it look perfect. Took it out and shot it again same ammo same rest and what a difference it made. I am a happy MKII owner now. Now I will steal the no drill scope mounts from my wife's Ruger and get the red dot on it. Hers is factory drilled so I will modify a Remington 760 Weaver base to fit her Ruger and hers will be ready to use again when the weather gets better for her to go shoot. I will use the Remington base because no one has the Ruger base and I want it back together. Not the first time I had to use the Remington base on a Ruger. Turned out to write a book.
