DistantFoe, I went with a company called SMI. www.smokelessmuzzleloading.com
is the website.
They build smokeless ML on the New England Firearms actions. I bought a used Pardner Shotgun for $85 to send them. They will put a 28" douglas barrel on for $319 plus $60 for a choate stock and $8 for a piece to fix the cocking hammer so you can cock it with a scope on.
They have been selling them since 1984. Long before Savage.
There a few other companies as well; New Ultra Light Arms (NULA), SwingLock, and BadBull. I heard bad reviews about the BadBulls, plus they are $3000 each. The Nula is supposed to be amazing I believe it has a Mcmillian Stock and you can get a Timney or Jewell Trigger. They are around $1100. I haven't heard anything about swinglock.
What I liked about the SMI is that you can shoot rifle bullets and it will cost me less than a savage.
If your going to shoot an inline it makes no sense to not go smokeless. It's legal in most states and you can shoot triple 7 or the other crap if it not legal. My Knight shoots pyrodex the best and it is the worst stuff to deal with so I'm going smokeless.
Remember, its still a muzzleloader and your not going to get 1/4" groups. If you can get less than an inch your doing great.
