Hi guys! I have a 930 that I have tried with multiple chokes and loads/shot sizes, it consistently patterns left about 4" at 30 yards. I have tried the factory Modified and full as well as a .660 turkey choke. Shot sizes ranging from 8s to lead bb to 00 buck (no tighter than full used with buckshot) with load weights ranging from 1oz-1.5oz. I plan on using this gun for a general purpose shotgun, squirrels/rabbits to coyotes (hence the lead bb). The elevation is perfect, just the left of center pattern. Anyone have any input on this?

Still waiting on a response from them. Im right handed and it does this even from a rested position, cast maybe?

If you are properly aligned behind the gun so you can accurately sight down the barrel and use the techniques of shooting off a bench with tight chokes following Neil Winston's protocol; you will be able to accurately assess the Point of Impact VS Point of Aim. If it is off laterally as you suspect, it will help if you can clearly show/explain how you determined that when you speak to Mossberg. Good luck and let us know what you determine and how Mossberg handles your issue.

They will have to see the gun. Industry patterning standards are from 40 yards, of course no wind. What is Mossberg's standard? You'll have to ask them.

Quote:
Point of Impact

We are asked on occasion about chokes that do not center the pattern exactly on the aiming point. Most shooters want a shotgun that centers the pattern exactly with the point of aim. Most shotguns are manufactured in theory to do this. The problem arises between theory and fact. It is not unusual to find shotguns that shoot high or low and to the right or left or a combination of these. Shotguns that pattern ½ above and ½ below the point of aim have what is commonly known as a 50/50 pattern. One that shoots ¾ of the pattern over and ¼ under the point of aim has a 75/25 pattern and so on. Certain guns are designed to give patterns other than 50/50. WE WILL ASSUME that you know if your gun was designed to give a pattern other than 50/50.

Some of the common reasons for off center patterns are listed below.

1-Defective choke tube

2-Bent barrel

3-Choke/barrel alignment

4-Loose barrel

5-Poor gun fit

6-FLINCH


This could also result from a combination of any of the above.

Well, for what you listed as your likely targets, with the possible exception of rabbits, if all else fails, there`s always a red dot or scope.

Not as far as the gun shooting where it is supposed to.
