Thread: Cause of split groups?

It is really like something is jumping around - your groups are good so likely not you- but try a different shooter and one who can shoot - its like something is moving -or as Mickey Duck is saying could be bedding -the barrel is jumping from side to side possibly - but those mounts what did they do and why with a dremel - looking at the job it does not look precision at all if one was trying to true a mount - look at the bedding if its okay well then try a different scope in those mounts for a start - if that holds correct consistent zero then likely the windage adjustment in the Steiner scope -still does it then try different mounts -- but if all your screws are correct torque then the windage adjustment could be the problem - sorry cant be more help - good luck you will just have to work thru a process of elimination - I fixed tractors for awhile and when I got to one that would not start the first thing I did was look in the diesel tank and with a torch did not even trust the gauge - one step at a time treat it as a process and start from real basics
