Sallee-bo, it seems that many on this message board are like those on the archery message board, meaning that if your bow ain't shooting 330 FPS you ain't no body. I think the same message is sent by all these well meaning muzzleloading enthusiasts on this thread. If you ain't shootin nothing but the latest 209, BH, perfect projectile, brand new muzzleloader that will throw a bullet out to 200 hundred yards, then you aren't up to date. But, to answer your question, yes there are conversion kits for your rifle both on line and at Knight dealers. But, rather than spend $ and worry about whether your gun is good enough, I recommend that you clean that gun up, make sure the breech plug and nipple are in working order, shoot about 80 grains of granular Pyrodex, with a good bullet (most any bullet), and you will be in business. The MK85 with that combination is a great gun and will do the job. Everything else is just dressing.
