I have both a Bob Jones and a Mojo, both are great shooting guns. Bob's action is a little longer and the Mojo guns have a shorter action, both are very accurate... I have shot the Bob Jones for about 7 years and have shot some great scores. But I was looking for a change and had a Mojo built. I am going to the MOJO full time and see if the change will get me a few more points. The Mojo is a great shooter, good turn around time on the build out, and if you have any issues, Joe is quick with a turn around fix. He has his own lathes and mills and can put almost any type of configuration on his barrels that you would want.
