Sportsmaster,
Bad news man,the smokeless concept in a Muzzleloader is a bust.Savage tried and didn't include very good data,and in some cases none at all.If you get one,be very careful as the burn characteristics of smokeless is vastly different then that of black powder and the equivalents.
Pressure spikes and all sorts of evil things can easily happen with smokeless in a front stuffer,due to moments inattention that wouldn't otherwise be a problem with Blackpowder because of volume density of the powder.Think about this.A thimble full of 2400 is about max in a .50 cal,will it even show up on the ram rod mark?The equivalent charge of Black powder will barely get the projectile out of the barrel.Also seating pressure is more critical,and if a guy were to short seat there may be a "crouquet effect" upon firing due to the air space,or a flash over,where all the powder is ignited at once instead of a rear forward train,resulting in a big pressure spike.
I have seen all sorts of twisted and unintentionally terminal disassembly's due to minor reloading errors with centerfires where very precise equipment is used,I shudder to think of what is possible using a volume measure in the field under stress of a hunt.Keep your eye on what happens with this concept a while,and see what happens.If it catches on and the bugs are done away with,jump on when you are ready is all I can advise.I really think Savage grabbed a dragon by the tail with this,and it soon will go away due to liability issues.
Cheers!Pat
