Yes i have one its a great gun but there are some thing i dont like its only a 4+1 shotgun and it needs high powered loads to cycle properly but very dependable. My buddy has a mossberg 930spx and i was messing with it and its tube extenction threads on perfectly to my weatheby so with a little modding of tube will hold more. But great gun.
I have a weatherby 459 TR in 20 gauge. My particular gun does not cycle with light loads. Cycling with heavy loads is good. I have not found a 20 gauge buckshot load to pattern well past 15 yards. I have found slug shooting at 100 yds with a rifled choke doable (for hunting use). Gun takes Beretta Mobil choke tubes.
