I had one of the original Thompson Center Contenders with several barrels, all of them 10 inch. Among them was a .44 mag and a .22 mag.
Every time I fired the .44 it felt like someone hit my elbow with a rubber hammer. It was much worse than model 29 or Super Blackhawk.
I really wanted the .22 mag barrel to work but the one I got was mediocre at best. Actually that is being too kind, it grouped around 4 inches at 25 yards and that with a scope.
I eventually traded it off and for some stupid reason traded for it back a year or two later. I guess I was hoping that it really wasn’t that bad but it was.
