T-Roy the 7-57 is almost the same as the 7-08. Still not a good idea on a contender frame. If you are looking for a cartridge that you can purchase factory ammo for, the 7-30 Waters is the way to go. I have that cartridge chambered in a rifle barrel for my TC. It works real good on deer and black bear. Total cost was just over $600.00 for the barrel, wood stock set, scope and mounts. It is a light weight and will still shoot a quarter at 100m.
