The accessories kit for this gun in my videos should work for your knight muzzy you can buy it in a kit you can find them at walmart TC accessories kit http://www.walmart.com/ip/Thompson-Cent ... t/17481679
My understanding is the knight muzzy uses a plastic sleeve like thing to hold the primer in place works like a weather shield just added stuff to buy if you ask me. Not sure if you can use the primers I use> cci 209 magnum regular shot shell primers. You may have to use the special muzzleloader primers. Knight muzzy can be very accurate with right setup just sux they felt the need to add the disc part that's what was their undoing. I would hate having to buy a box of them along with my primers just added expense. You may be able to get a conversion breech plug for your gun ! They make em just search around if you don't like the disc part like me.
I would try & find out if that muzzy has magnum capabilities I would think so but with no manual I would play it safe. No more then 120Gr pyrodex & no more then 90Gr Blackhorn 209 that would be the equivalent of the pyrodex but outperform it with lower pressure & better FPS + energy. I would try Blackhorn 209 try a load at 80 then move up by fives not passing 90. This may give you a idea on what kind of sabot you might want to use http://www.chuckhawks.com/barnes_bullet ... loader.htm This should help you sort out sabots & be able to tell one kind from another http://www.barnesbullets.com/products/c ... -accuracy/ buy em in bulk from MMP sabots are lots cheaper that way & that way you know what you got. Unlike the ones with sabot - bullet in packs! I use the spit-fire T-EZ in my gun with hph-24 Barnes are the only ones I know of that tell you what sabot is supplied in the ones that come with bullet + sabot in a 10 or 20 pack. For a knight like yours I would start with this sabot hph-12 I would think hph-24 would not fit as tight as you would want leading to loss in accuracy. If it did however fit to tight aka can't push it down I would go with hph-24 as long as its not to easy to push down. Anyways hope this info helps you not sure about your experience level with inlines or muzzy but better to have all the info needed then not enough. Good luck & be safe.
