I have a Gen 1 T/C Contender that I'd like to buy a new barrel for. I won it about 20 years ago at a Pheasants Forever event. It came with the .45LC/.410 barrel which I still have and will keep. Right after I got it I wanted to buy a barrel in a "fun" caliber so I picked up a Super 14" in .357 Maximum. This caliber is dying so I want to sell that barrel and buy something that will be around for a while. I thought a .45-70 would be cool but I hear that the recoil is nasty. I have plenty of .38's and .357 mags around so I don't need anymore of these. Any recommendations for a different caliber?
