I bagged an antlerless deer a couple months ago with my new CVA Optima muzzleloading pistol in the PA early muzzleloading (antlerless) season. Its a great gun and is very affordable. Ballistic equivalent to a 44 Magnum. Perhaps the ideal gun for your liking. There are a few photos on the bragging board.
