I'm gonna stick my neck out a hair with this, but myself and others are shooting smokeless in the Huntsman with the Metrics Unlimited breech plug. The key to the whole thing is it HAS TO BE A SABOT and it has to be the MU breech plug. The sabot is your safety valve. Overpressure will blow past the sabot. It will not blow by with a full bore load as with a cast or jacketed bullet. The nice thing is you can shoot all day and never have to clean. I got a nice buck last winter with the Huntsman, but I obeyed Michigan law and used a 209 primer, Harvester sabot, .451 240 gr. XTP and two Triple Seven 50 gr. pellets. You can replicate that load with 3031 or other rifle powders. Check Savage's website for their smokeless ML loads.

This opens a whole new world of possibilities. I haven't got a clue why H&R hasn't gotten together with MU and come out with a factory smokeless muzzleloader. I love it because I can spend a lot of time with my Huntsman without an equal time cleaning.
