I like my Contender in 45-70. SSK 14" w/ arrestor break. I shoot 300 grn JHp's Trapdoor handloads. Fun and accurate. I tried some of my Sharps 405 Cast loads and they are pretty stout.
I have been shooting this barrel for a lot of years. I did have one of the 12" Hunter barrels with factory break but ran on to this one so I sold the 12" TC barrel.
