I was shooting from a bench sitting. I have tried over the hood of my truck, and standing with the same results. I have never had a shotgun do this before. I have had the xtrema since the first year they came out. I just started loading my own shells so with that comes testing, this is how I figured my pattern was off. I will look into what you said, thanks for the info.
Was this the first time you had patterned your gun since you have had it? Or was this just the first time with your new reloads?
If you gun was not shooting like this before, and now suddenly is... then the answer is as simple as trying a different load.
If this is your first trip to the board with it however, then this may well have been happening all along and you didn't realize it. It may well be the fit of the gun, as aforementioned, but it may too be that the choke tubes are not installed correctly (read: squarely). Just like an insert in an arrow can be slightly askew, causing irradic arrow flight, so too can tubes be installed off center. More common with newer Remingtons and some other lower end models, but its not unheard of in the three Big "B" companies.
