I would be willing to bet that once you get a good trigger on it,you're groups will improve a lot. It's mighty hard to shoot any firearm with a heavy stiff trigger.

I have the fully rifled cantilever barrel and nikon 2-7 x 32 prostaff on the gun right now...its satisfactory shooting at best with the hornaday sst sabots.
A trigger job is an absolute must. I think after this season I am going to have a trigger job done to the 500 and my Model 700 270 and go from there.
