What kind if deal? The Nova is the one pumpgun I have no real experience with (other than sampling a few loads). My go-to Turkey gun is a Mossberg 835 12 gauge. It has a 10 gauge barrel which opens the shot up a little, then stabilizes it. For long-distance tight patterns it can't be beat- at least not by anything I have tried, and I have tried them all. Awesome for long-range geese and turkeys. If the ranges are going to be decent I grab the 870 SuperMag every time.
I've had them all other than the Nova. Both the Mossbergs and the Remingtons are good guns, but I'd take an 870 over the Mossbergs. Remingtons tend to be a little tighter out of the package and a little bit better fit-and-finish. As a hunter the clincher has always been the slug barrels. My 870's always shoot tighter than my Mossbergs, a lot tighter. I had a bead on a Marine Magnum from the cop-shop my BIL works at, but the officers snapped them all up.
HTH.
