It's a muzzle loader..............Knighthawk 50 caliber. Been discontinuedfor years. It's like new and shoots Shock Wave 250 grain bullets in front of 70 grains of Triple Seven. 2" groups at 50 yards:-) I converted it to use shotgun primers. The Contender is a 14" barrel 45/70!! Now that's a handfull. I also have a 12" barrel in 45/70 but it's even too unpleasant for me to shoot it and I think recoil is cool on handguns:-) Zeiss Z-Point is the only reflex sight I've used that will withstand that punishment.
