The best IMO is a Remington 209-4 - but of course Remington not longer makes it...
I have been shooting the new Winchester Triple Se7en primer - It really seems to function well, but they are expensive /100 - the only reason I have them is Wal-Mart had them on sale for $2/100
You might get a package of regular Winchester W209's the mildest you can get and try them.
There is a thread down the line on 209's might read some of that...

#11 mag caps and the Nobel #1075 caps are hotter than a Musket cap, but do not light for the same duration - the musket cap will provide sparks longer. IMO the 1075 is awful hard to beat.
